1SVR730700R2100

ABB CM-MSS.13S Thermistor Motor Protection Relay, Part Number 1SVR730700R2100, a reliable industrial motor temperature monitoring and protection device designed for electrical control panels, motor control centers (MCC), industrial automation systems and machinery protection applications.

The ABB CM-MSS.13S belongs to ABB's CM-MSS series of thermistor motor protection relays. It is designed to monitor motor winding temperatures using compatible PTC thermistor sensors, helping protect electrical motors against excessive temperature conditions arising from overload, inadequate cooling, frequent starting and abnormal operating environments.

The relay operates with rated control supply voltages of 110–130V AC or 220–240V AC at 50/60 Hz, providing flexibility for different industrial control circuits. It features one changeover (SPDT) output contact rated at 250V / 4A for controlling compatible electrical switching and protection circuits.
