SIRIUS S00 direct starter — busbar-mount variant
The Siemens 3RA2110-1BD15-1BB4 is a SIRIUS direct-on-line starter in size S00, designed specifically for snapping onto 60 mm busbar systems rather than DIN rail.
Mounting and panel fit — busbar snap-on, not DIN rail
This starter fastens by snapping onto 60 mm busbar systems — a different footprint from standard 35 mm DIN-rail-mounted starters. The mounting position is vertical only. Dimensions are 45 mm wide, 155 mm deep, and 203 mm tall, with clearance requirements of 50 mm upwards, 20 mm forwards, 20 mm at the side, and 10 mm downwards. No backward clearance is needed. If your panel layout was built around a DIN-rail starter, this busbar-clip variant will not drop in without a mounting adapter or a change to the busbar support structure. Verify the busbar spacing and the vertical orientation before committing the BOM line.
