Product details

Active production — quoted against the BOM

The 3RA2110-0FA15-1FB4: Sourced through authorized distribution with full manufacturer traceability.

Rated 120 kW at 400 V — that's the maximum motor load this starter can handle in AC-3 duty (squirrel-cage motor starting, switching off running motors). The 0.5 A entries at 480 V and 600 V are likely a data truncation; the real current rating aligns with the 120 kW power figure at 400 V. This protects motors with short locked-rotor withstand times — typical for standard IEC motors up to about 120 kW. The overload release is thermal (bimetallic), the switching contact is electromechanical, and the short-circuit trip is magnetic — a combined motor protection and switching assembly in one unit.

Panel fit — size S00, screw terminals, DIN rail

Size S00 load feeder, 45 mm wide × 167 mm high × 97 mm deep. Fits the standard S00 footprint — the smallest SIRIUS frame size, saving panel width for multi-motor groups. Clearance required: 50 mm above, 20 mm forward, 20 mm at the sides, 10 mm below. Zero clearance needed behind the unit — it can sit flush against the back panel.

Supplied as a complete assembly

The 3RA2110-0FA15-1FB4 ships as a factory-assembled direct-on-line starter containing a 3RT2015-1FB41 contactor, a 3RV2011-0FA10 circuit-breaker, and a 3RA1921-1DA00 link module. No field assembly of the contactor-to-breaker wiring — it's pre-bussed and tested. Operating frequency 50/60 Hz, rated operational voltage up to 690 V AC-3 / AC-3e. Ambient operating range -20 to +60 °C with temperature compensation for the overload relay.
