ABB 1SVR740885R3300 Three-Phase Monitoring Relay

The ABB CM-MPS.21P is a versatile three-phase monitoring relay from the CM series, offering comprehensive protection and monitoring capabilities for industrial applications. It monitors critical phase parameters such as over/undervoltage, phase unbalance, phase failure, and interrupted neutral, allowing for proactive maintenance and prevention of system downtime. The relay's adjustable threshold values and 0.1-30 second tripping delay provide flexibility in responding to various fault conditions. Its Easy Connect Technology with push-in terminals simplifies installation and maintenance, while the sealable transparent cover protects against unauthorized changes. Suitable for monitoring single-phase mains, this relay is a robust solution for ensuring the stability and reliability of electrical systems.
