The ICM517 is UL Rated as a Type 2 device and must be installed
before the equipment it is intended to protect. It can be installed at
the A/C disconnect or an indoor/outdoor electrical panel. Suitable
for use on a circuit capable of delivering not more than 10,000 rms
symmetrical amperes, 240V max, when protected by a circuit breaker
rated 15A-60A maximum and 120V minimum. Device wires should be
kept at a minimal length to increase response time and effectiveness
of the control. Contains no serviceable parts.
