What snaps onto a 60 mm busbar
The 3RA2110-0HD15-1FB4 is a SIRIUS direct online starter in size S00 — a pre-assembled combination of a contactor, overload relay, and circuit-breaker on a common busbar adapter. It snaps onto 60 mm busbar systems, not a DIN rail, so the panel layout needs that specific busbar spacing. The 24 V coil matches standard control voltages in many industrial panels.
What's in the box — supplied sub-assemblies
This starter ships with the contactor (3RT2015-1FB41), the link module (3RA1921-1DA00), the circuit-breaker (3RV2011-0HA10), and the busbar adapter (8US1251-5DS10) already integrated. The overload release is thermal bimetallic; the short-circuit trip is magnetic. Mounting position is vertical only. Clearance requirements: 50 mm upward, 20 mm forward, 10 mm downward, and 20 mm at the side — no clearance needed backward. Ambient operation range is -20 to +60 °C.
