Reversing starter for 60 mm busbar systems — SIRIUS S00
The 3RA2210-1KH17-2BB4 is a Siemens SIRIUS reversing starter in size S00, designed to snap directly onto 60 mm busbar systems — no separate DIN-rail adapter needed for the main power feed. It ships as a pre-assembled unit with the contactor (3RT2017-2BB42), link module (3RA2911-2AA00), and busbar adapter (8US1251-5DT11) included — one order code, one line item on the BOM.
Rated power and current — AC-3 duty at common line voltages
Rated operating frequency is 50/60 Hz, so it works on either mains standard without derating.
Mounting and clearances — busbar snap-on with vertical orientation
Fastens by snapping onto 60 mm busbar systems; mounting position is vertical only. Minimum clearances: 50 mm upwards, 32 mm forwards, 10 mm at the side and downwards — the backwards clearance is 0 mm, so the back face sits flush against the busbar. Dimensions are 155 mm deep, 90 mm wide, 260 mm high — a compact footprint for the S00 frame class.
Termination and environment — spring terminals, wide temperature range
Main current circuit uses spring-loaded terminals — no screw torque to verify, just strip and push for solid or ferruled stranded wire. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C.
