PRODUCT DESCRIPTION
ABB 1SVR450056R0000 - Single-Phase Voltage Monitoring Relay
This ABB CM-ESS.1S series single-phase voltage monitoring relay provides continuous supervision of AC or DC system voltages for overvoltage and undervoltage conditions. It integrates adjustable thresholds and time delays to prevent equipment damage and ensure operational stability in critical industrial control circuits, power distribution systems, and machinery protection applications. The device features a self-supplied design and a single changeover output contact for alarm or control actions.
