Product Description

The CM-ESS.2S, a product from ABB's CM series, is a single-functional voltage monitoring relay. It 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.

This device employs a RMS measuring principle for both DC and AC voltages, offering four measuring ranges: 3-30 V, 6-60 V, 30-300 V, and 60-600 V. It operates on the open-circuit principle.

The CM-ESS.2S is configurable for over- or undervoltage monitoring with an adjustable hysteresis ranging from 3 to 30% of the threshold value and a tripping delay that can be adjusted from instantaneous to 30 seconds (0, 0.1-30 s).

A sealable transparent cover is available as an accessory for protection against unauthorized changes. The device features screw connection technology with double-chamber cage connection terminals.
