ICM531 (3-Phase Delta 480VAC or Wye 277/480VAC) 

The ICM530 Series is 2 models of Type 1 and Type 2 three-phase Surge Protective Devices for three-phase Delta and three-phase Wye configurations. 

When a surge occurs, the ICM three-phase surge suppressor will absorb the surge up to the specified limitations of the device. ICM incorporates superior thermally protected metal oxide varistor technology into the three-phase 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 suppressors can be installed as a Type 1 or Type 2 device for both indoor and outdoor applications.
