SIRIUS reversing starter for 60 mm busbar systems
The Siemens 3RA2210-1DD15-2AP0 is a SIRIUS reversing starter in size S00, designed specifically for snapping onto 60 mm busbar systems. It integrates a reversing contactor and overload relay into a single assembly, saving panel space compared to wiring two separate contactors and a relay. This unit ships with the supplied contactor (3RT2015-1AP02) and link module (3RA1921-1DA00) pre-assembled, reducing wiring errors and installation time on the line.
Motor ratings and trip class across voltages
This is the standard for most general-purpose induction motors up to 3 hp.
Panel fit and clearance requirements
The envelope is 204 mm high, 90 mm wide, and 155 mm deep — the depth is the critical dimension for shallow enclosures. Mounting is vertical only; the fastening method clips directly onto 60 mm busbar systems without additional brackets. Minimum clearances around the unit: 50 mm upwards, 32 mm forwards, 10 mm downwards, and 10 mm at the sides. The backwards clearance is 0 mm — it can sit flush against the back panel. These gaps are for ventilation and arc-flash containment; ignoring the upward clearance will reduce the overload relay's thermal accuracy.
Operating temperature range is -20 to +60 °C with temperature compensation active across the same band, meaning the overload trip curve stays accurate even in hot panel environments. Storage and transport limits extend from -50 to +80 °C.
