ICM Controls ICM531 3 Phase I/II Surge Protective Device
The ICM531 is a 3-PHASE SURGE PROTECTIVE DEVICE, 480VAC (DELTA) OR 277/480VAC (WYE)
When a surge occurs, the ICM three-phase surge protective device will absorb the surge up to the specified limitations of the device. ICM incorporates superior thermally protected metal oxide varistor technology into the threephase surge suppressors, which allows for safe disabling of the surge elements when a surge exceeds the thermal limits of the device. There is a single status light on the controls which identifies operational status when illuminated.
The ICM 3-phase surge protective device can be installed as a Type 1 or Type 2 device for both indoor and outdoor applications.
