NettetThe thermistor motor protection relay CM-MSS.21 is used to monitor the temperature of motors or generators equipped with PTC resistor sensors type A. The sensors are built-in into the motor windings, measuring the motor heating. In case of an increase of the temperature in the motor, the resistance of the PTC sensors will increase as well. NettetThe CM-MSS.41S 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 2 c/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. hard thing on bottom of foot
