CM-EFS Voltage Window Monitoring Relay - Single Phase AC/DC

The voltage window monitoring relay CM-EFS.2 can be used for the simultaneous monitoring of over- (>U) and undervoltages (

The voltage to be monitored (measured value) is applied to terminals B-C. Open- or closed-circuit principle as well as an adjustable ON A or OFF tripping delay are configurable.

Monitoring of DC- and AC voltages from 3-600 V
RMS measuring principle
