Product details

SIRIUS direct starter for 60 mm busbar systems

The Siemens 3RA2110-0KD15-1BB4 is a SIRIUS direct online starter in size S00, designed specifically for snapping onto 60 mm busbar systems — a space-saving alternative to panel-mounting individual contactors and overloads. The assembly ships with the contactor (3RT2015-1BB41), link module (3RA1921-1DA00), and busbar adapter (8US1251-5DS10) included — a matched set that saves BOM line-item management.

The fastening method is for snapping onto 60 mm busbar systems — the starter clips directly onto the busbar without a separate mounting plate, reducing panel depth. Mounting position is vertical only; clearance requirements are 50 mm upwards, 20 mm forwards, 10 mm downwards, and 20 mm at the side, with 0 mm backwards clearance needed. Dimensions are 155 mm deep by 45 mm wide by 203 mm high — the 45 mm width fits a standard 45 mm busbar pitch without overhang.
