S00 reversing starter for 60 mm busbar panels
The Siemens SIRIUS 3RA2210-1FD15-2BB4 is a factory-assembled reversing starter in size S00, designed specifically for snapping onto 60 mm busbar systems — common in panel builds where the busbar doubles as the mounting rail and the main power distribution spine. It ships with the contactor 3RT2015-1BB42 and the link module 3RA1921-1DA00 already integrated, so the reversing interlock and mechanical linkage arrive as a single orderable unit rather than a field-assembled kit.
Physical envelope and panel clearances
The body measures 155 mm deep, 90 mm wide, and 204 mm tall — a compact footprint for a reversing starter in the S00 frame. Clearance requirements are specified: 50 mm upward, 32 mm forward, 10 mm downward, and 10 mm at the side, with zero backward clearance needed — useful when packing multiple starters on a busbar section. Mounting position is vertical only, and the fastening method is a snap-on clip for 60 mm busbar systems — no DIN rail adapter required.
Termination and environmental limits
Main current circuit connections use screw-type terminals — a familiar interface for panel wiring with ring or fork lugs, no special tooling needed. Operating temperature range is -20 to +60 °C, with storage and transport limits from -50 to +80 °C, so it holds up in unconditioned warehouses or shipping containers during a tire-curing press line build.
