Three phase monitoring relays

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 V AC 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).
