3RT1017-1BB42 motor starters - contactors Siemens Sirius
The Siemens 3RT1017-1BB42 is a compact 3-pole power contactor belonging to the classic, highly reliable SIRIUS 3RT1 legacy series. Built within the space-saving Size S00 frame, this contactor is engineered for switching three-phase electric motors up to 5.5 kW at 400 V (rated for an operational current of 12 A under inductive AC-3 conditions).
Operating on a standard 24V DC coil, it comes pre-equipped with 1 integrated Normally Closed (1 NC) auxiliary contact, making it ideal for immediate safety interlocking or control feedback loops. Robust screw terminals provide secure, long-lasting conductor routing. Its climate-proof housing is optimized for high-temperature durability, allowing side-by-side mounting up to 60°C without derating inside compact electrical panels.
