Single-phase monitoring relays

Ordering details

CM-range - Current and voltage monitoring relays
Single-phase voltage and current monitoring relays protect sensitive equipment and control
systems against undervoltage (brownout) or undercurrent events or overvoltage or overcur-
rent events. Different units with adjustable or fixed threshold values (trip points) are
available.
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
2CDC 251 054 V0011 Easy Connect Technology (push-in terminals) with excellent vibration resistance.
