The 3RA2110-1HS15-1BB4: The overload release is thermal bimetallic, trip class 10, with a magnetic short-circuit trip for instantaneous fault clearing.
Busbar snap-on mounting and panel footprint
Fastens by snapping onto 60 mm busbar systems using the supplied busbar adapter 8US1251-5DS11 — no separate mounting plate required for busbar integration. Dimensions 155 mm depth × 45 mm width × 212 mm height fit standard S00 feeder slots; clearance requirements are 50 mm upwards, 20 mm forwards, 20 mm at the side, 10 mm downwards, and 0 mm backwards. Mounting position is vertical; the main current circuit uses spring-loaded terminals for tool-less wiring of the power conductors.
Supplied subcomponents and compliance traceability
The starter ships with contactor 3RT2015-2BB41, link module 3RA2911-2AA00, and busbar adapter 8US1251-5DS11 — each orderable separately for spares or replacement. Storage and transport temperature range -50 to +80 °C, operating range -20 to +60 °C with temperature compensation active across the full operating band.
