1SVR630884R4300 | ABB CM-MPS.43 Multifunctional Three-phase Monitoring Relay

Product Overview: Multifunctional Three-Phase Monitoring Relays

Type: CM-MPS.43
The CM-MPS.43 three-phase monitoring relay monitors key phase parameters, including phase sequence, phase failure, over- and undervoltage, and phase unbalance. Suitable for mains with a frequency of 45–440 Hz, the device is available in two terminal versions: screw connection or push-in terminals for tool-free installation.
