ABB Phase, Voltage Monitoring Relay, 3 Phase, DPDT, 300 → 500V ac, DIN Rail

The CM-PVS.x1 are monitoring relays for three-phase mains. They monitor the phase parameters phase sequence, phase failure, over- and undervoltage. The threshold values for over- and undervoltage are adjustable.

Monitoring of three-phase mains for phase sequence (can be switched off), phase failure, over- and undervoltage
Threshold values for over- and undervoltage are adjustable as absolute values
Tripping delay can be adjusted or switched off by means of a logarithmic scale
ON-delayed or OFF-delayed tripping delay selectable
Powered by the measuring circuit
True RMS measuring principle
2 c/o (SPDT) contacts
3 LEDs for status indication

Use this double-pole, double-throw (DPDT) voltage monitoring relay from ABB to protect your equipment and circuits from electrical damage. The device is designed for 3-phase circuits and works by tracking the phase parameters (sequence and failure) of the system it's connected to. It monitors for overvoltage and undervoltage in the range of 300 to 500V AC and triggers the switches to turn off the circuit when a fault occurs. As it consumes just 25mA of electrical current, this relay is an energy-efficient safety solution for your industrial and commercial systems.
