Description
Overload relay 12.5...50 A Electronic For motor protection Size S2, Class 5E...30E Stand-alone installation Main circuit: Straight-through transformer Auxiliary circuit: Screw Manual-Automatic-Reset Internal ground fault detection solid-state overload relay SIRIUS 3RB3 for inverse-time delayed protection of loads with normal and heavy starting against excessive temperature rises due to overload, phase unbalance or phase failure.
Due to the wide current setting ranges and various tripping characteristics, complete series of motors are covered with just a few types. With their low heat loss, they are particularly energy-efficient and help to reduce the temperature rise in the control cabinet. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous areas (ATEX) are a matter of course. The 3RB31 version offers enhanced functions, such as an integrated, electrical remote reset or ground fault detection, to name but a few.
Can be supplied with different setting ranges of the overload release and with different trip classes. They are available with screw or spring-loaded terminals for fast, maintenance-free and vibration-proof connection, as well as for stand-alone installation.
The accessories consistently fit all sizes from S00 to S3.
Simple, efficient and always up to date - SIRIUS modular system.
