Busbar-mount direct starter, S00 frame
The Siemens 3RA2110-0JD15-1AP0 is a SIRIUS direct-on-line starter in the S00 size, designed to snap onto 60 mm busbar systems — no DIN rail adapter needed when the busbar is already in the panel. The unit ships with a 3RT2015-1AP01 contactor and a 3RA1921-1DA00 link module pre-assembled — it arrives as a single orderable assembly, not a kit.
Panel fit and mounting clearances
Mounting position is vertical only. Minimum clearance around the unit: 50 mm upwards, 20 mm forwards, 20 mm at the sides, 10 mm downwards, and 0 mm backwards — the back face sits flush against the busbar. Operating temperature range is -20 to +60 °C; storage and transport limits extend from -50 to +80 °C.
Sourcing and lifecycle — active production
Main circuit connections use screw-type terminals, standard for panel wiring. The S00 frame size matches the circuit-breaker size S00, so the upstream protection coordinates with the starter footprint.
