Product Code: CM-MSS.32P

The Thermistor Motor Protection Relay is designed to monitor PTC temperature sensors using one sensor circuit. It features short-circuit detection and dynamic interrupted wire detection. The relay operates on a rated control supply voltage of 24 V AC/DC and has 2 CO (SPDT) output contacts rated at 250 V / 4 A. The relay also includes interrupted-wire monitoring and can be reset automatically, manually, or remotely after the failure has been resolved. It is equipped with push-in terminals for easy installation.
