SIRIUS 3R L.V. motor control gear includes motor protection circuit breakers, contactors and overload relays up to 100A, with a minimum fault rating of 50KA throughout the range. In addition, load feeders and time relays are included in the comprehensive range.

The SIRIUS 3R range incorporates innovation down to the last detail. In the contactors, for example, there are coils with four terminals for ultra-simple wiring in all feeder combinations. This is extremely long lasting with up to two million electrical switching cycles.
The SIRIUS 3R range is the first control gear with a screwless fixing technique (Cage Clamps). The Cage Clamp technique, that has proved so successful for the Siemens 8WA2 terminal blocks, is now available for all size S00 terminals and for the auxiliary power supply terminals of the S0 to S3 devices. The range has received the international iF award for "good design".
