PRODUCT DESCRIPTION
ASEA BROWN BOVERI 1SVR440711R0100 - Single-phase Current Monitoring Relay
This ABB CM-ESS.1S series single-phase current monitoring relay provides continuous supervision of AC/DC current levels within industrial control circuits. Engineered for overcurrent and undercurrent detection, it integrates user-configurable threshold settings and two potential-free changeover output contacts for precise process control, fault signaling, and equipment protection. Primary applications include motor load monitoring, power distribution system safeguarding, and general machinery protection.
