1SVR740700R2200

ABB CM-MSS.23P Thermistor Motor Protection Relay, Part Number 1SVR740700R2200, a reliable industrial motor temperature monitoring and protection device designed for electrical control panels, motor control centers (MCC), industrial machinery and automation systems.

The ABB CM-MSS.23P belongs to ABB's CM-MSS series of thermistor motor protection relays and is specifically designed to monitor motor winding temperatures through compatible PTC thermistor sensors. It helps protect industrial electric motors against overheating caused by excessive load conditions, insufficient cooling, repeated starting, high ambient temperatures and abnormal operating conditions.

The relay operates with rated control supply voltages of 110–130V AC or 220–240V AC, offering compatibility with different industrial control circuits. It incorporates two changeover (DPDT) output contacts rated at 4A at 230V AC for compatible resistive loads, allowing integration into motor shutdown circuits, fault indication systems and industrial automation equipment.
