Single-Phase Surge Protection

The ICM517A is a NEMA Type 4X enclosed Type 2 Surge Protective Device (SPD) designed to protect valuable single-phase equipment by dissipating momentary voltage spikes and transient power surges. Applications include the protection of motors, electronics, air conditioning systems, appliances, refrigeration, and more. The tried and true, preexisting industry favorite ICM517 SPD recently received an update, which prompted the designation of an "A" to the end of the preexisting part number. With 100,000's of ICM517's installed in the field, ICM stayed true to the rugged & reliable design of the existing "go to" SPD, the new ICM517A Type 2 Surge Protective Device is now constructed even more robust.
