SIRIUS S00 direct-on-line starter — busbar-mount, CLASS 10
The Siemens 3RA2110-1CD15-1AP0 is a SIRIUS direct-on-line starter in size S00, designed for snapping onto 60 mm busbar systems — no DIN rail adapter needed when the busbar is already in the panel. Width is 45 mm, so it occupies one standard 45 mm busbar slot; depth is 155 mm, height 203 mm — check the enclosure depth before committing the gland plate layout.
What's in the box — supplied contactor and link module
Comes with the 3RT2015-1AP01 contactor and the 3RA1921-1DA00 link module pre-assembled — the link module bridges the contactor to the overload relay, saving wiring time and reducing loop faults. Main circuit terminals are screw-type, rated 690 V, sized for the S00 frame. Wire up clean with ring or fork lugs; the terminal torque spec is standard for this frame class. Rated for vertical mounting only — the ambient operating range is -20 to +60 °C, with a 50 mm clearance above and 20 mm forward needed for heat dissipation and finger-safe access.
No official successor or cross-reference to a different order code — the 3RA2110-1CD15-1AP0 is the current build standard for this S00 direct starter configuration.
