1SVR730885R3300 ABB - CM-MPS.21S

The CM-MPS.21S is a sophisticated three-phase monitoring relay designed to safeguard electrical equipment from common power supply issues. This device continuously monitors the three-phase network, providing reliable protection against phase sequence errors, phase failures, overvoltage, and undervoltage conditions. Featuring two changeover (2c/o) contacts, the CM-MPS.21S allows for flexible integration into various control circuits, enabling immediate response to detected anomalies. The adjustable time delay, ranging from 0.1 to 30 seconds, prevents nuisance tripping caused by transient voltage fluctuations. Specifically designed for three-phase networks with a neutral conductor (L1-L2-L3-N), it supports a voltage range of 3x180-280VAC. This ensures compatibility with a wide range of industrial power systems. Its robust design and precise monitoring capabilities make it an essential component for maintaining the integrity and reliability of electrical systems. By promptly detecting and responding to power supply irregularities, the CM-MPS.21S minimizes downtime and protects valuable equipment from potential damage. This advanced monitoring relay is ideal for applications in manufacturing, automation, and power distribution.
