1SVR730700R2200

ABB CM-MSS.23S Thermistor Motor Protection Relay, Part Number 1SVR730700R2200, an advanced industrial motor temperature monitoring and protection device designed for electrical control panels, motor control centers (MCC), industrial machinery and automation applications.

The ABB CM-MSS.23S belongs to ABB's CM-MSS series of thermistor motor protection relays and is specifically engineered to monitor motor winding temperatures through compatible PTC thermistor sensors. This device helps protect industrial electric motors against overheating caused by excessive loads, inadequate cooling, frequent starting, high ambient temperatures and abnormal operating conditions.

The relay operates with rated control supply voltages of 110–130V AC or 220–240V AC at 50/60 Hz, making it suitable for different industrial electrical control circuits. It incorporates two changeover (SPDT) output contacts rated at 250V / 4A, allowing connection to motor shutdown circuits, fault indication devices and automation control equipment.
