Electronic overload relay 4...16 A for motor protection, size S00, CLASS 10E. Main circuit connection: spring clamp, auxiliary circuit: spring clamp, manual-automatic RESET. The electronic overload relay SIRIUS 3RB3 provides current-dependent protection for consumers with normal and heavy starting against excessive heating due to overload, phase asymmetry, or phase failure. With large current setting ranges and different tripping characteristics, a complete series of motors can be covered with just a few types. Their low power loss makes them particularly energy-efficient and contributes to lower heating in the control cabinet. Global approvals (e.g., IEC and UL/CSA) and applications in explosion-prone environments (ATEX) are standard. Available with various setting ranges for the overload relay and different tripping classes. They come with screw or spring clamp connections for quick, maintenance-free, and vibration-resistant installation, as well as for standalone mounting. The accessories are compatible across all sizes from S00 to S3. Simple, efficient, always up to date - the SIRIUS system modular concept.
