Catalog Description
CM-SRS.21P Current monitoring relay 2c/o, B-C=3mA-1A RMS, 24-240VAC/DC
Long Description
The CM-SRS.21P is a single-functional current monitoring relay from the CM single-phase monitors range.
This monitoring relay operates with a rated control supply voltage of 24 - 240 V AC / DC and has a 2 c/o
(SPDT) output with contacts rated at 250 V / 4 A. It provides a 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.21P is configurable for over- or undercurrent monitoring. The hysteresis is
adjustable within a range of 3 to 30 % of the threshold value and the tripping delay is adjustable over a
range of instantaneous to 30 s (0, 0.1-30 s). A sealable transparent cover for protection against
unauthorized changes is available as accessory. The device offers maintenance free Easy Connect
Technology with push-in terminals.
