The CM-SRS.M is an electronic current monitoring relay that protects single-phase mains (DC or AC) from over- and undercurrent from 3mA to 15A.
All devices are available with two different terminal versions. You can choose between the proven screw connection technology (double-chamber cage connecting terminals) and the completely tool-free Easy Connect Technology (push-in terminals).
