SIRIUS reversing starter, size S00
The 3RA2210-0FH15-2BB4 is a Siemens SIRIUS reversing starter — a compact, pre-assembled unit combining a contactor pair, thermal overload relay, and link module in one package for forward/reverse motor control. The size S00 frame keeps the footprint tight: 155 mm deep, 90 mm wide, 260 mm tall, with a vertical mounting position specified.
Busbar snap-on and wiring
This starter snaps directly onto 60 mm busbar systems — no DIN rail adapter needed, which saves rail space and speeds panel assembly. Main circuit connections use spring-loaded terminals — push-in for solid or ferruled stranded wire, no screw torque to verify. Clearance requirements: 50 mm upward, 32 mm forward, 10 mm to the side and downward, zero backward — plan the enclosure layout accordingly.
Overload protection and trip class
Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C, so it handles unheated warehouses and truck beds in winter. Rated frequency is 50/60 Hz — no derating needed between the two common line frequencies.
What's in the box
The reversing starter ships as a complete assembly: it includes a 3RT2015-2BB42 contactor, a 3RA2911-2AA00 link module, and a 3RA2913-1DB2 RS assembly kit — all pre-configured for reversing duty.
