Snap-on reversing starter for 60 mm busbar systems
The Siemens 3RA2210-0BH15-2AP0 is a SIRIUS reversing starter in size S00, designed specifically for snapping onto 60 mm busbar systems — a compact footprint that saves panel width compared to building a reversing pair from separate contactors and a mechanical interlock. It ships as a pre-assembled unit including the 3RT2015-2AP02 contactor, the 3RA2911-2AA00 link module, the 8US1251-5DT11 busbar adapter, and the 8US1250-5AT10 RS assembly kit — everything needed for a reversing motor feeder in one order code.
Class 10 thermal overload and magnetic short-circuit trip
The overload release is thermal bimetallic, Class 10 trip class — it protects standard squirrel-cage motors during start-up without nuisance tripping on normal acceleration, but clears quickly enough to prevent winding damage on a locked-rotor condition.
Mounting position is vertical only, with a fastening method designed for snapping onto 60 mm busbar systems — the busbar adapter and RS assembly kit are included, so no separate busbar clips or DIN-rail adapters are needed. Clearance dimensions: 50 mm upwards, 32 mm forwards, 10 mm at the side, and 10 mm downwards — no space required behind the unit (0 mm backwards). The overall envelope is 260 mm high, 90 mm wide, and 155 mm deep. Main current circuit connections use spring-loaded terminals — no screw torque verification needed, which speeds panel wiring and reduces the risk of loose connections under thermal cycling.
Active production and sourcing posture
No stock-holding claim — each order is quoted individually. RoHS compliance date is 10/01/2009 — the part meets the EU RoHS directive for substances of concern, which simplifies import documentation for EU-bound shipments.
