ICM Controls Single Phase Surge Protector

The ICM517A is a rugged, NEMA Type 4X enclosed Type 2 Surge Protective Device (SPD) engineered to safeguard your valuable single-phase equipment. By actively dissipating momentary voltage spikes and transient power surges, it ensures the longevity and safe operation of air conditioning systems, refrigeration units, motors, appliances, and sensitive electronics.

Building on a Legacy of Trust The new ICM517A takes the tried-and-true performance of the industry-favorite ICM517 and elevates it to a new standard of durability. With hundreds of thousands of legacy units successfully installed in the field, we kept the reliable performance professionals trust and housed it in a significantly more robust, cast-aluminum enclosure.
