Product details

Reversing starter for 60 mm busbar systems

The Siemens 3RA2220-4BD27-0BB4 is a SIRIUS reversing starter in size S0, designed to snap directly onto 60 mm busbar systems — no separate mounting plate needed. The unit includes a supplied contactor (3RT2027-1BB40) and link module (3RA2921-1BA00), so it arrives as a fully assembled reversing pair with mechanical interlock.

Mounting and panel fit

Clearance requirements: 50 mm above, 32 mm in front, 10 mm below, and 10 mm at the side for airflow and arc venting. Mounting position must be vertical; ambient operating range is -20 to +60 °C, which covers most indoor panel environments.
