Reversing starter for 60 mm busbar systems — S00 frame, 0.2 A AC-3
The Siemens 3RA2210-0BS15-2BB4 is a SIRIUS reversing starter in the S00 load feeder size, designed for snapping onto 60 mm busbar systems. It integrates a supplied contactor (3RT2015-2BB42), link module (3RA2911-2AA00), and busbar adapter (8US1251-5DS11) into a single assembly for forward/reverse motor control. Spring-loaded terminals on the main current circuit allow tool-less wiring of the power connections, reducing installation time in panel builds. The operating frequency is 50/60 Hz, covering standard industrial mains supplies.
Mounting and clearance — vertical on 60 mm busbars, 155 mm depth
Mounting position is vertical, with the unit fastening directly onto 60 mm busbar systems via the supplied adapter. Physical dimensions are 155 mm depth, 90 mm width, and 230 mm height — the depth is the critical dimension for enclosure depth selection. Required clearances for heat dissipation and wiring access: 50 mm upwards, 32 mm forwards, 0 mm backwards, 10 mm downwards, and 10 mm at the side. The zero backward clearance means the unit can be mounted flush against a back panel or enclosure wall without additional spacing. Operating temperature range is -20 to +60 °C, with storage and transport range from -50 to +80 °C. The vertical mounting orientation is mandatory for proper thermal performance of the bimetallic overload relay.
Lifecycle and sourcing — current production, quoted to order
The unit carries the SIRIUS product brand and is designed per IEC/EN 60947-4-1 for motor starters.
