Why Choose the ABB CM-MSS.13S Thermistor Motor Protection Relay?
The ABB CM-MSS.13S 1SVR730700R2100 is a compact and reliable thermistor motor protection relay designed to monitor PTC temperature sensors embedded in electric motors and other temperature-sensitive equipment. As part of the ABB CM-MSS thermistor motor protection relay series, it provides dependable overtemperature monitoring to help protect motors against excessive thermal stress.
The CM-MSS.13S features one PTC sensor circuit and operates according to the closed-circuit principle. When the monitored PTC thermistors indicate an excessive temperature condition, the relay changes its output state so that the associated control circuit can stop the motor, initiate an alarm or perform another protective action.
This model operates from a rated control supply of 110–130 V AC or 220–240 V AC and provides one changeover (SPDT) output contact rated at up to 250 V / 4 A. Automatic reset restores the relay after the fault condition has cleared, while screw terminals and a slim 22.5 mm housing simplify installation in industrial control panels.
Key Advantages
- Dedicated PTC thermistor motor protection relay for temperature supervision.

Reliable PTC Thermistor Motor Protection
PTC thermistors embedded in motor windings respond to increasing temperature by sharply increasing their electrical resistance when the specified response temperature is reached. The ABB CM-MSS.13S monitors this sensor circuit and uses its relay output to signal an overtemperature condition, allowing the control system to disconnect or protect the motor.
The automatic reset function allows the CM-MSS.13S to return to its normal operating state after the thermal fault has cleared and the PTC sensor circuit has returned to the appropriate condition. This makes the relay suitable for automated machinery and motor-control systems where reliable thermal protection and straightforward integration are required.
Typical Applications
- Three-phase electric motor thermal protection.
- Pumps, fans and ventilation equipment.
- Compressors and refrigeration machinery.
- Conveyors and material handling systems.
- Industrial production and processing machinery.
- Motor control centres and electrical control panels.
- OEM machinery and industrial automation systems.
