Why Choose the ABB CM-MPN.62P Three-Phase Monitoring Relay?
The ABB CM-MPN.62P is a multifunctional three-phase monitoring relay designed to provide reliable electrical network supervision and fault detection in industrial power distribution and automation systems. As part of the ABB CM-MPN monitoring relay series, it monitors critical three-phase supply parameters to help protect electrical equipment against voltage abnormalities, phase failure, incorrect phase sequence and phase unbalance.
This advanced monitoring relay combines several protective monitoring functions in one compact device, simplifying electrical panel design and reducing the need for separate monitoring components. It provides adjustable overvoltage and undervoltage thresholds, phase sequence supervision, automatic phase sequence correction functionality and configurable relay outputs. Its push-in connection terminals support quick, secure and maintenance-free wiring.
Designed for three-phase 450–720 V AC systems operating at 50/60 Hz, the CM-MPN.62P features two configurable changeover contacts and an adjustable tripping delay of 0 or 0.1–30 s. Its compact DIN rail-mounted construction makes it suitable for electrical distribution boards, industrial motor control panels and automated machinery requiring continuous supply monitoring.

Reliable Three-Phase Supply Monitoring and Electrical Protection
The ABB CM-MPN.62P continuously monitors the condition of a three-phase electrical supply to detect abnormalities that could disrupt industrial processes or damage connected equipment. By supervising voltage levels, phase sequence, phase failure and phase unbalance, the relay provides an effective means of identifying potentially harmful supply conditions before they lead to prolonged equipment downtime.
The relay's adjustable monitoring thresholds and configurable output contacts allow it to be integrated into motor control circuits, alarm systems and industrial automation equipment. Its selectable automatic phase sequence correction function supports applications where phase rotation must be managed, while the adjustable tripping delay helps prevent unnecessary switching caused by short-duration voltage disturbances.
With its 450–720 V AC operating range, compact DIN rail design and push-in connection technology, the CM-MPN.62P offers a practical solution for engineers and panel builders requiring dependable three-phase monitoring in higher-voltage industrial electrical installations.
