ABB AB Voltage Monitor Relay, Dpdt, 4A, 230Vac; Product Range Abb 1SVR740830R0400

The CM-ESS.2P is a single-phase voltage monitoring relay with a 2 c/o (SPDT) output rated for 250 V / 4 A AC and 24 V / 4 A DC, designed for over- or undervoltage protection in control circuits. It operates from a 24-240 V AC/DC supply and supports four measurement ranges: 3-30 V, 6-60 V, 30-300 V, and 60-600 V. The relay features adjustable tripping delay from 0.1 to 30 seconds and adjustable hysteresis from 3% to 30% of the threshold. It is mounted on DIN rail (TH35-15 or TH35-7.5 per IEC 60715), has screwless push-in terminals accepting 0.5-1.5 mm² wires, and complies with EN 50178, IEC/EN 60255-27, UL 508, and CAN/CSA C22.2 No.14. The device has an IP50-rated housing, operates from -20 to +60 °C, and is RoHS compliant.
