ABB CM-ESS Multifunction Voltage RMS Monitoring Relay 1SVR730830R0500

·         The CM-ESS.MS is a multifunctional 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.

·         The CM-ESS.MS offers selection of over- or undervoltage monitoring, open- or closed-circuit operating principle, with or without latching function.

·         The hysteresis is adjustable within a range of 3 to 30 % of the threshold      value.

·         The tripping delay and the start-up delay are 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.
