1SVR740700R2100

ABB CM-MSS.13P Thermistor Motor Protection Relay, Part Number 1SVR740700R2100, an industrial motor temperature monitoring and protection device designed for electrical control panels, motor control centers (MCC), machinery protection and industrial automation applications.

The ABB CM-MSS.13P belongs to ABB's CM-MSS series of thermistor motor protection relays. It is designed to monitor motor winding temperatures through compatible PTC thermistor sensors, helping protect electric motors against excessive temperatures resulting from overload, inadequate cooling, frequent starting, high ambient temperatures and abnormal operating conditions.

The relay supports rated control supply voltages of 110–130V AC and 220–240V AC at 50/60 Hz, making it suitable for different industrial control circuits. It incorporates one changeover (SPDT) output contact with a rated operational current of 4A at 230V AC under AC-12 conditions.
