SIRIUS 3RA2 reversing starter — what's in the box
The 3RA2215-0FD15-2BB4 is a SIRIUS non-fused reversing motor starter in size S00, factory-assembled as a matched set: a 3RT2015-1BB42 contactor, a 3RV2011-0FA15 circuit-breaker with thermal bimetallic overload (Class 10) and magnetic short-circuit trip, a 3RA1921-1DA00 link module, a 8US1251-5DS10 busbar adapter, and a 3RA2913-1DB1 RS assembly kit.
Mounting and panel fit — snaps onto 60 mm busbar
Fastens by snapping onto 60 mm busbar systems in a vertical mounting position — the 90 mm width and 200 mm height fit standard S00 feeder slots; depth is 155.1 mm, with 20 mm clearance required above and 10 mm below for wiring and heat dissipation. Operating temperature range is -20 to +60 °C, storage -50 to +80 °C, transport -55 to +80 °C — the -20 °C floor means it's fine for unheated plant areas in moderate climates, but not for deep-freeze or outdoor Arctic installs without a heated enclosure.
