1SVR730830R0400 – CM-ESS.2S Voltage monitoring relay, 24-240V AC/DC ABB Voltage Monitoring Relays
24-240V AC/DC, measuring 3-30V, 3-60A, 30-300V and 60-600V The CM-ESS.2S is a single-functional voltage monitoring relay from the CM single-phase monitors range. This monitoring relay operates with a rated control supply voltage of 24 – 240 V AC / DC and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. It provides a RMS measuring principle for DC and AC voltages with 4 measuring ranges: 3-30 V, 6-60 V, 30-300 V and 60-600 V and works according to the open-circuit principle. The CM-ESS.2S is configurable for over- or undervoltage monitoring. The hysteresis is adjustable within a range of 3 to 30 % of the threshold value and the tripping delay is adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers screw connection technology with double-chamber cage connection terminals. 1SVR730830R0400 – CM-ESS.2S Voltage monitoring relay, 24-240V AC/DC ABB Voltage Monitoring Relays is a genuine ABB electrical component designed for industrial automation, motor control, and power distribution
