The Thermistor Motor Protection Relay is designed to monitor PTC temperature sensors using one sensor circuit. It operates based on the closed-circuit principle and features 2 LEDs for visual indication. The relay works with a rated control supply voltage of 110-130 VAC/220-240 VAC. It has a 1 CO (SPDT) output contact rated at 250V/4A. The relay also includes interrupted-wire monitoring, and it will automatically reset after the failure has been resolved. Additionally, it is equipped with double-chamber cage connection terminals for secure connections.
