Siemens asked contractors for everything they wanted in an enclosed safety switch. Their
input helped create the toughest, most reliable, most hassle-free enclosed safety switch in the
business – the Siemens Type VBII Safety Switch. It’s a switch that’s right for any commercial,
industrial or special use application. The Siemens Safety Switch line offers a list of important
features that gives contractors a competitive edge:

General and Heavy Duty switches
feature a time-proven design
Like the time-proven Vacu-Break design,
the Siemens VBII double-break switching
action breaks the arc in two places. This
reduces heat generation and increases
switching speed by doubling the breaking
distance. The result is enhanced performance
and increased longevity. We also provide the
most visible blade design available today.
Unlike conventional knife blade switches,
the blades are self-aligning to ensure positive
contact. In addition, they have no wear and
friction point since the “electrical hinge”
has been eliminated. The result is a very
fast, positive and reliable switching action
for even the most severe applications.
One tough switch:
More rugged and durable in
demanding applications
Siemens engineers tackled the problem of
designing a switch that would stand up under
the most demanding industrial conditions,
such as those in steel mills and mining
operations. These environments require a
switch that must work reliably and safely
in the midst of falling liquids, airborne
fibers, dust, metal particles, coolants and
other contaminants.
Tested and retested
All Siemens safety switches have been
tested not only to meet but to exceed
all UL requirements. These tests include
those for general purpose enclosed
switches and those designed for more
specialized purposes where applicable.
The result is a rugged, reliable design
that will provide superior performance
in a wide variety of applications.
Siemens now offers a complete line of enclosed switches featuring unique and innovative
designs that are unparalleled in the industry.

General and heavy duty features
Type VBII Safety Switch
Application
General duty switches
General Duty Switches are intended for applications where
reliable performance and continuity of service are needed,
but where duty requirements are not severe and usual
service conditions prevail. These switches are intended
for use primarily with supply circuits rated 240V AC or less
where the available fault current is less than 100,000Awhen
used with Class R or T fuses or 10,000A max. when used with
Class H fuses.
Application
Heavy duty switches
Heavy Duty Switches are intended for use in applications
where:
1. Rugged construction, reliable performance, continuity of
service and ease of maintenance are emphasized
2. Available fault currents higher than 10,000A are likely to
be encountered, such as in manufacturing plants, mass
production industries and commercial, institutional and
other large buildings served by network systems or
transformers of higher capacities
3. System voltage is 600V AC or DC max
4. A Type 12 or 4 / 4X enclosure is required
Short-circuit withstand ratings
General duty switches
Suitable for use on systems capable of delivering not more
than 100,000 RMS symmetrical amperes of fault current
when Class R fuses are installed. Also rated 100,000 AC max.
in 200-600A ratings with Class J and T fuses.
Short circuit withstand ratings
Heavy duty switches
Suitable for use on systems capable of delivering not
more than 200,000 RMS
1)
symmetrical amperes of fault
current when Class J or R fuses are installed except the
800 and 1200A switches, which are suitable for use on
circuits capable of delivering not more than 200,000 RMS
symmetrical amperes of fault current when Class L fuses
are installed. 100-1200A switches with Class T fuses and
field adapter kit are also 200,000 RMS symmetrical rated.
1)
100,000 RMS for 60 A compact non-fusible switches.
Fuses
General duty switches
Fusible switches will accept the following UL class fuses:
Class H
Class K
Class R—Class R fuse clip rejecter kits are required.
Class T—200-600A switches (200A switches require field
adapter kit)
Heavy duty switches
Fusible switches will accept the following UL class fuses:
Class H
Class K
Class R—Class R fuse clip rejecter kits are required

field convertible
Class L—800 and 1200A switches only
Class T—100-1200A switches (100 and
200A switches require an adapter kit)
Cover interlocks
General duty switches
Defeatable cover interlocks on Type 1 switches and 60-600A
Type 3R switches prevent the switch door from being
opened when in the ON position.
Heavy duty switches
Defeatable dual cover interlocks are standard on all heavy
duty switches. Prevents cover from being opened when
switch is in the ON position and prevents switch from being
turned ON when door is opened.
Padlocks

Application
4 & 6 pole switches are commonly used as a disconnecting means for two
speed, two-winding motors. Fused switches provide both over current and
short-circuit protection. Non-fusible switches normally provide a local
disconnection means for two-speed motors, which are remote from their motor
controller. 4 pole switches are also used in 3-phase, 4-wire circuits when a
switching neutral is required. All 4 & 6 pole switches are service entrance rated.

Description and application
Double throw safety switches are intended to transfer loads from one power
source to another. All two- and three pole double throw switches are suitable
for use as service equipment. All are UL listed. Switches are rated for use on
systems up to 10,000A when protected with Class H fuses or 100,000A when
protected with Class R or Class T fuses. They can also be used to connect a
single source of power to either of two loads. In this application it is necessary
to field modify fusible switches so that the fuses are on the load side of the
switching mechanism. A cover interlock is provided on all ampere ratings. The
operating handle may be padlocked in the OFF position.

Fuse application and selection data
Siemens enclosed safety switches are
designed for fuse versatility. Although
Siemens is not a manufacturer of fuses,
once the type of fuse needed for a
particular application is determined, it’s
easy to select an appropriate switch.
The proper fuse type for the application
is selected using the following
parameters:
Voltage requirements
Conductor ampacity
Horsepower requirements
Maximum available RMS fault-current
UL fuse class when specified
The compatible fusible safety switch is
selected following these parameters:
System voltage requirements
Fuse amp ratings
Available fault current
UL fuse class
Environmental conditions
Number of poles required
One-Time Fuses
One-time fuses are standard for use in
situations calling for 1200 amperes or
less with maximum voltages for 250
or 600 volts. Specially designed,
current carrying links are connected
to contact pieces at the ends of the
enclosure. When an overload occurs,
the circuit quickly opens and the arc
is quenched by granular insulating
material that surrounds the current
carrying links.
Available in all classes.
Current Limiting Fuses
This design offers the highest degree of
circuit protection among fuses. Inside,
usually copper or silver alloy links are
embedded in pure quartz sand between
heavy copper end blocks. The special
design is fast-acting and interrupts
during the first half-cycle of a fault.
This causes a limitation of both
fault peak current and let-through
current.
Available in Classes J, L, R and T.
Dual-element Time-delay Fuses
Dual-element fuses may have time
delay designation since these fuses
employ two distinctly separate types
of elements. One provides overload
protection with time delay. (UL states
that time delay means having a
10-second operating delay at 500
percent of fuse label rating.) The
second provides short circuit protection
similar to a single-element fuse.
Dual-element fuses are most frequently
used on motor loads.
52 53

Fuse application and dimensions
Class R and H fuses
Class R application: Over-current and
short-circuit protection of motors and
transformers, service entrance equipment,
feeder and branch circuits.
(General Purpose Protection)
Class R rejection: A UL Class R fuse kit is
required that rejects lower-rated fuses
(H and K).
Class J fuses
Application: Current limiting protection
to a wide variety of applications,
Panelboards, Switchboards, Busway
and Feeder Circuits.
Rejection: Its unique dimensions
prevent the substitution of another fuse.
Class H fuse dimensions

Type VBII Safety Switch
Ratings and test requirements
Enclosed switch load ratings
The primary functions of a fusible
enclosed switch are to carry current
continuously, to provide over current
and short-circuit protection, to
be capable of disconnecting the circuit,
and to provide means for mounting
fuses. Safety switches may also have
other capabilities covered by load break
ratings (in contrast with no-load
disconnect switches), such as standard
and maximum horsepower ratings
and the ability to withstand the
maximum I2t energy let-throughs
of fuses.
All Siemens safety switches are capable
of continuously carrying their full-rated
nameplate current at rated voltage.
This capability is directly attainable
in no-fuse switches and in fusible
switches when the fuses are replaced
with copper bars, without exceeding
permissible temperature rise.
Fuses are capable of carrying their
rated current in open air. Under this
condition the fuses will not open
and will not exceed permissible
temperature rise. When fuses are used
in a switch or other enclosure, a higher
ambient temperature is caused by the
switch heat and fuse-generated heat.
Since fuses are thermal acting by
design, they will not carry full current
rating at higher ambient temperatures.
To assist users of fusible equipment,
UL requires each fusible switch to carry
the statement “Continuous load current
not to exceed 80% of the rating of the
fuses employed.” Good electrical
practice may require even further
deratings depending on the type of
fuse, load, altitude and ambient
temperature of the switch location.
Load break ratings
All Siemens safety switches are
load break rated. The load break
rating is assigned by UL after the
switching unit has successfully
performed the following tests for
general use enclosed switches:
Load break ratings
12X current rating
In addition to the required UL overload
testing, all Siemens VBII Safety
Switches have been tested at twelve
times rated current at 600V AC to
assure compliance to automotive and
other heavy industry requirements.
Horsepower ratings
All Siemens safety switches, where
appropriate, are horsepower rated. The
assignment of such ratings is made by
UL only after the switching unit has
undergone tests to determine its
acceptability. In addition, the unit must
successfully perform on an overload
test series which includes repeated
interruption of the locked rotor current
of the motor for which it is to be rated
as follows:
Horsepower ratings
Most switches have two or more
ratings for a particular voltage and
current. Siemens safety switches are
UL listed for design E horsepower
ratings. With Siemens safety switches
no derating is required in most cases.
Depending on the switch and its
application, various ratings have been
achieved. All Siemens switches include
a complete list of the ratings on the
inside of the cover.
Horsepower rating charts
The number and variety of horsepower
ratings that can be applied to a
switching unit makes it impractical, in
most instances, to list all such ratings
on the front of the unit. Siemens does,
however, provide this data by means of
a chart on the inside cover.
Horsepower rating range
UL test procedure include ratings up to
500 HP. Siemens safety switch units in
appropriate sizes have successfully
passed the locked rotor current
interrupting test series for ratings
through 500 horsepower at both 480
and 600 volts AC and through 50
horsepower at 600 volts DC.
Maximum horsepower ratings
The maximum horsepower rating is
based upon the largest rating of a
time delay fuse: 1) which can be
incorporated in the switch and 2)
which will permit the motor to be
started. Since the fuse has extra time
delay, it can hold the starting current
of a larger motor longer than a
standard fuse.
Standard horsepower rating
This rating is assigned to a switch after
it has successfully completed the locked
rotor test series, on the basis of the
largest standard fuse rating: 1) which
can be incorporated in the switch and
2) which will permit the motor to be
started. The standard fuse does not
have a designed time delay to allow for
motor starting currents.

Multiple-voltage
horsepower ratings
A switch may have additional standard
and maximum horse-power ratings
for different voltages. A switch that is
horsepower rated at 240V AC or 250V
DC may also have horsepower ratings
for motors on 120V AC or 125V DC
circuits.
Multi pole horsepower ratings
A switch may have horsepower ratings
applicable to the same current and
voltage ratings but with fewer poles
if the switch is investigated and found
suitable for the assigned rating.
Short-circuit withstandability
UL test procedures for switches and
fuses have been expanded to provide
realistic standards of performance
with respect to clearing high-level
fault currents.
These revised standards deal with the
control of destructive energy in the
shorted circuit. Two types of potential
damage are characteristic of high-level
short-circuits: mechanical and thermal.
Mechanical damage is caused by the
electromagnetic force surrounding
conductors; thermal damage is the
result of excessive current during
the fault-clearing time.
The UL fuse standard defines
maximum instantaneous peak
let-through current (lp) and maximum
destructive energy let-through (I
2
t)
for each fuse (except Class H).
Applications of fuses and safety
switches on systems having more
than 10,000A are available. Short
circuits require selections of the proper
UL-listed fuses and switches capable
of withstanding I
2
t let-throughs. See
chart below for withstand ratings on
Siemens switches.
I
2
t Rated
Suitability tests for service with
ClassH, R, J, L and T fuses have been
conducted. Representative switches
with test fuses connected in series
with each switch were subjected to
I
2
t let-through values in excess of
the capacities of the largest fuses
acceptable by the switches.
To pass the test, the switch must
remain operable after being
closed into a high-amp available
short-circuit current. The test fuse
is sized so that higher levels of
let-through current and energy will
be reached than would ever occur
during normal usage in the field.
