3RN1010-2CB00 SIEMENS

The Siemens 3RN1010-2CB00 is a phased-out thermistor motor protection standard evaluation unit, designed to safeguard motors against overheating. As a legacy product, it has been superseded by the 3RN2010-2CA30 model, which offers enhanced features and performance. This evaluation unit is equipped with one normally open (NO) and one normally closed (NC) contact, providing versatile signaling options for control systems. It operates on a 24 V AC/DC power supply, ensuring compatibility with a wide range of industrial environments. The unit utilizes spring-type terminals for secure and reliable electrical connections, simplifying installation and maintenance. Thermistor motor protection relays, like the 3RN1010-2CB00, are crucial components in preventing motor damage caused by excessive temperatures, extending motor lifespan and reducing downtime. While the 3RN1010-2CB00 is no longer actively manufactured, it may still be found in existing installations. For new applications, the recommended replacement is the 3RN2010-2CA30. This successor offers improved functionality and aligns with current industry standards, ensuring optimal motor protection.
