The CM-MP Series three-phase monitoring relays from ABB Electrification Products are designed for reliable monitoring of three-phase mains. These relays provide essential functions such as over- and undervoltage monitoring, phase failure detection, phase unbalance monitoring, and phase sequence monitoring. They ensure the safe operation of machines and installations by continuously monitoring critical parameters, which helps prevent potential damage due to electrical faults. The relays are available for rated voltage levels up to 820 VAC and feature two terminal options: screw terminals and push-in terminals, allowing for flexible installation methods. The devices are equipped with an easy-to-use front face potentiometer for straightforward adjustments. The CM-MP Series is suitable for applications requiring robust monitoring solutions in three-phase systems, making them a practical choice for engineers seeking reliability and safety in their electrical installations.
Three-phase Monitoring Relays
Reliable monitoring of three-phase mains
The reliable and continuous monitoring of three-phase networks guarantees trouble-free and economic operation of machines and installations. The most multifunctional three-phase monitoring relays in the electronic relays and controls assortment are the CM-MPS/N monitoring relays for rated voltage levels up to 820 VAC and 400 Hz. Additionally, a variety of economic and cost-efficient three-phase monitoring relays are offered in this range with specialized functionality. Most devices are available with two different terminal versions. You can choose between the proven screw connection technology (double-chamber cage connection terminals) and the completely tool-free Easy Connect Technology (push-in terminals).
