ABB CM-EFS.2P VOLTAGE MONITORING RELAY CONTROL 24 - 240 V AC/DC 2CO PUSH IN TERMINALS

Product Code: CM-EFS.2P

The Voltage Monitoring Relay is designed for both over- and undervoltage monitoring. It uses a RMS measuring principle to measure DC and AC voltages in four different ranges: 3-30 V, 6-60 V, 30-300 V, and 60-600 V. This relay operates with a rated control supply voltage of 24 - 240 V AC/DC. It has two CO (SPDT) outputs with contacts rated at 250 V / 4 A. The relay features push-in terminals for easy installation. It offers window monitoring for both over- and undervoltage conditions, allowing you to select ON or OFF delay. It can operate in either an open or closed circuit configuration and can be used with or without a latching function. The tripping delay and start-up delay of the relay are adjustable within a range of instantaneous to 30 seconds (0, 0.1-30 s).
