ABB CM-PAS.31S Three-Phase Monitoring Relay

The three phase monitoring relays CM-PAS.x1 monitor the phase parameters phase sequence, phase failure as well as phase unbalance.
All devices are available with two different terminal versions. You can choose between the proven screw connection technology (double chamber cage connection terminals) and the completely tool free Easy Connect Technology (push in terminals).

The three phase monitoring relays CM-PAS.x1 are designed for use in three-phase mains for monitoring the phase parameters phase sequence, phase failure as well as phase unbalance.

The CM-PAS.x1 provides an adjustable ON-delay and work according to the closed-circuit principle.
