1SVR740700R0200

ABB CM-MSS.22P Thermistor Motor Protection Relay, Part Number 1SVR740700R0200, an 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.22P belongs to ABB's CM-MSS series of thermistor motor protection relays and is designed to monitor motor winding temperatures through compatible PTC thermistor sensors. It helps protect industrial motors against excessive temperature conditions resulting from overloads, inadequate ventilation, frequent starting, excessive ambient temperature and other abnormal operating conditions.

The relay operates with a rated control supply voltage of 24V AC/DC and features two changeover (DPDT) output contacts rated at 250V / 4A. These contacts enable integration with motor protection circuits, alarm indication systems and control equipment.
