CM-MPS.41S Three-phase monitoring relay 2c/o, 0,0.1-30s, L1-L2-L3=3x300-500VAC

The CM-SRS.11S is a single-functional current monitoring relay from the CM single-phase monitor range. This monitoring relay operates with a rated control supply voltage of 110–130 V AC and has a 1 c/o (SPDT) output contact rated at 250 V / 4 A. It provides an RMS measuring principle for DC and AC currents with 3 measuring ranges: 3–30 mA, 10-100 mA, and 0.1–1 A, and works according to the open-circuit principle. The CM-SRS.11S is configurable for over- or undercurrent monitoring, and the hysteresis is adjustable within a range of 3 to 30% of the threshold value. A sealable, transparent cover for protection against unauthorized changes is available as an accessory. The device offers screw connection technology with double-chamber cage connection terminals.
