The CM-SFS.22S 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 to 240 VAC/VDC 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: 0.3 to 1.5 A, 1 to 5 A and 3 to 15 A. The CM-SFS.22S offers window (over and undercurrent) monitoring as well as selection of ON or OFF delay, open or closed circuit operating principle, with or without latching function. The output contacts can be configured as 1x2 c/o (SPDT) (common signal) or 2x1 c/o (SPDT) (separate signal for minimum and maximum thresholds) operation. The hysteresis is fixed at 5% of the threshold value. The tripping delay and the start-up delay are adjustable over a range of instantaneous to 30 s (0, 0.1 to 30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers screw connection technology with double chamber cage connection terminals.
