Reversing starter, S00 frame, 1.6 A AC-3 — what's in the box
The 3RA2215-1AA16-2BB4 is a Siemens SIRIUS reversing starter in size S00 — a pre-assembled combination of a reversing contactor pair, a thermal overload relay, and the interlocking link module, all on a single 90 mm wide base. It ships with the 3RT2016-1BB42 contactor and the 3RA1921-1DA00 link module already integrated.
Clearance and panel fit — S00 footprint
Dimensions: 170 mm high, 90 mm wide, 97 mm deep. Minimum clearances around the unit: 50 mm upward, 32 mm forward, 10 mm downward, and 10 mm at each side — no clearance needed behind the DIN rail (0 mm backward). These are the ventilation and arc-space requirements; crowding them derates the thermal overload or risks nuisance tripping. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C. The overload relay includes temperature compensation over the full operating range.
