Single-/multifunctional monitoring relays

Ordering details

CM-range - 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 devices in the ERC 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.
2CDC251015V0012 All devices are available with two different terminal versions. Choose between screw connec-
tion technology (double-chamber cage connection terminals) and the completely tool-free

CM-PFS.P Easy Connect Technology (push-in terminals) with excellent vibration resistance.
