Description
About the CM-ESS.1S
About the CM-ESS.1S
The ABB CM-ESS.1S voltage monitoring relay (SKU: 1SVR730830R0300) is a single-phase monitoring device from ABB's CM series, designed to detect under-voltage, over-voltage, and supply failures across a wide measurement range of 3–600 V RMS. With a universal auxiliary supply of 24–240 V AC/DC, a 1 C/O (SPDT) output contact rated at 4 A, and a compact 22.5 mm DIN rail housing, the CM-ESS.1S suits a broad range of industrial control panel and power quality applications where reliable voltage supervision is critical.
