PRODUCT DESCRIPTION
ABB 1SVR440720R0200 - Single-Phase Undervoltage Monitoring Relay
This ABB CM-ESS.1P series electronic monitoring relay is engineered for accurate undervoltage detection in single-phase AC or DC electrical systems. It provides continuous voltage supervision, activating two independent change-over contacts upon deviation from user-defined thresholds. Designed for integration into industrial control panels, motor control centers, and power distribution units, it ensures system integrity and equipment protection in essential automation and safety applications.
