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 based on the closed-circuit principle and has three LEDs for visual indication. It is compatible with control supply voltages of 110-130 VAC and 220-240 VAC. The relay has two CO (SPDT) output contacts rated at 250 V/4 A. It also includes interrupted-wire monitoring functionality. After a failure has been resolved, the relay can be reset automatically, manually, or remotely. The double-chamber cage connection terminals ensure secure and reliable connections.
