The CM-ESS.1S 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 to 240 VAC/VDC and has a 1 c/o (SPDT) output contact rated at 250 V/4 A. It provides a RMS measuring principle for DC and AC voltages with 4 measuring ranges: 3 to 30 V, 3 to 60 A, 30 to 300 V and 60 to 600 V and works according to the open circuit principle. The CM-ESS.1S is configurable for over or undervoltage monitoring, the hysteresis is adjustable within a range of 3 to 30% of the threshold value. 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.
