What this reversing starter carries
The Siemens 3RA2210-1GE15-2BB4 is a SIRIUS reversing starter in size S00 — a factory-assembled pair of contactors with a mechanical interlock and a thermal overload relay, all on one DIN rail footprint. The Class 10 trip curve means it protects standard squirrel-cage motors during startup without nuisance tripping on normal acceleration.
What comes in the box
This reversing starter ships with the contactor 3RT2015-2BB42 and the link module 3RA2911-2AA00 already integrated — no separate ordering of interlock kits or wiring between contactors. Termination is spring-loaded on the main current circuit, so you push in ferruled stranded wire or solid conductor — no screwdriver torque to check later. The S00 footprint is 90 mm wide, 204 mm tall, 97 mm deep — fits standard 200 mm deep enclosures with room for gland plates.
