The current monitoring relays of the CM series protect single-phase networks (DC or AC) against
overcurrents and undercurrents between 3 mA and 15 A. The devices with the maximum measuring range
of 1 A are available in two different connection versions. You can choose
between the proven screw connection technology (double-chamber box connection terminals)
and the tool-free Easy Connect connection technology (push-in terminals). Devices
with a maximum measuring range of 15 A are available with screw connection technology.
