Product details

The Siemens 3RA2115-1BD15-1BB4 is a non-fused motor starter from the SIRIUS family, size S00, designed as a direct starter with a thermal bimetallic overload release.

This unit snaps onto 60 mm busbar systems, making it suitable for panel builds where compact, tool-free mounting on standard busbar grids is required. Mounting position is vertical only, with a width of 45 mm and depth of 155.1 mm, so it occupies a single 45 mm slot on the busbar. The supplied contactor is a 3RT2015-1BB41, and the link module is 3RA1921-1DA00; the busbar adapter 8US1251-5DS10 is included for the 60 mm system.

Frequently asked questions

What is the difference between 3RA2115-1BD15-1BB4 and a 3RV1011 circuit-breaker-based starter?

The 3RA2115 is a non-fused motor starter combining a contactor and overload relay, while a 3RV1011 is a circuit breaker with integrated overload protection. The 3RA2115 requires upstream short-circuit protection; the 3RV1011 provides both overload and short-circuit protection in one device.
