The CM series current monitoring relays protect single-phase networks (DC or AC) from overcurrents and undercurrents between 3 mA and 15 A. The devices with a 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 measuring range of up to 15 A are available with screw connection technology.
