Description：
The Siemens 3RN2011-1BA30 is a temperature monitoring relay from the SIRIUS 3RN2 series, specifically designed for thermistor-based motor protection.
This 3RN2011-1BA30 relay monitors motor winding temperature via PTC thermistors, providing direct and accurate thermal protection. When the temperature exceeds a defined threshold, the relay trips and disconnects the motor, preventing overheating and potential damage.
