Part Number: CM-MSS.11S
Manufacturer Code: 1SVR730720R1400
Multiples of: 1 | Minimum Order: 1
The CM-MSS.11S belongs to the CM-MSS thermistor motor protection relay range. It operates with a rated control supply voltage of 24 - 240 V AC / DC and has a 1 n/c + 1 n/o (SPDT) output with contacts rated at 250 V / 4 A. It features one sensor circuit to monitor PTC temperature sensors and works according to the closed-circuit principle. The sensor circuit of the CM-MSS.11S is interrupted-wire monitored and the relay will be reset automatically after the failure has been removed. This protection relay is certified according to the ATEX directive 94/9/EC. The device offers screw connection technology with double-chamber cage connection terminals.
