The SIRIUS 3RB2 electronic overload relay provides current-dependent protection of loads with normal and heavy starting against impermissibly high heating due to overload, phase unbalance, or phase failure. With large current setting ranges and different tripping characteristics, a wide range of motors can be covered with just a few types.

These relays are particularly energy-efficient, contributing to less heating in the control cabinet. They come with worldwide approvals (e.g., IEC and UL/CSA) and are suitable for applications in potentially explosive atmospheres (ATEX). Available with different setting ranges of the overload release and various tripping classes, they feature screw or spring-cage connections for fast, maintenance-free, and vibration-proof installation. The accessories fit all sizes S6 to S12.

Simple, efficient, and always up-to-date - the SIRIUS modular system.
