ABB Phase Monitoring Relay, 3 Phase, DPDT, DIN Rail

The CM-PAS.x1 are monitoring relays for three-phase mains. They monitor the phase parameters phase sequence, phase failure and phase unbalance. The threshold value for phase unbalance is adjustable

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