Overload relay 3...12 A electronic for motor protection size S00, CLASS 10E. Main circuit contactor: spring-loaded terminal, auxiliary circuit: spring-loaded terminal, manual-automatic RESET. Electronic overload relay SIRIUS 3RB3 for current-dependent protection of consumers with normal and heavy starting against excessively high heating due to overload, phase asymmetry, or phase failure. With large current adjustment ranges and different tripping characteristics, a complete series of motors can be covered with just a few types. With their low power loss, they are particularly energy-efficient and contribute to lower heating in the control cabinet. Worldwide approvals (e.g., IEC and UL/CSA) and applications in explosion-hazardous environments (ATEX) are standard. Available with various adjustment ranges for the overload relay and different tripping classes. They come with screw or spring-loaded connections for quick, maintenance-free, and vibration-resistant connections, as well as for standalone installation. The accessories are compatible across all sizes from S00 to S3. Simple, efficient, always up-to-date - the SIRIUS modular system.
