1SVR730700R0200

ABB CM-MSS.22S Thermistor Motor Protection Relay, Part Number 1SVR730700R0200, an industrial motor temperature monitoring and protection device designed for electrical control panels, motor control centers (MCC), automation systems and machinery protection applications.

The ABB CM-MSS.22S belongs to ABB's CM-MSS series of thermistor motor protection relays. It is specifically designed to monitor motor winding temperatures through compatible PTC thermistor sensors, helping protect motors against overheating caused by overload conditions, insufficient cooling, frequent starting and abnormal operating temperatures.

The relay operates with a rated control supply voltage of 24V AC/DC and incorporates two changeover (DPDT) output contacts rated at 250V / 4A. Its dual changeover contact configuration enables integration into motor shutdown circuits, fault signaling systems and industrial control applications.
