Reversing starter for 60 mm busbar systems
The Siemens 3RA2210-1DD15-2BB4 is a SIRIUS reversing starter in size S00, designed specifically for snapping onto 60 mm busbar systems — a common distribution layout in European panel builds where the busbar serves as both the power rail and the mechanical mount. The Class 10 trip characteristic means it will hold in during a normal motor start (up to about 10 seconds of locked-rotor current) but trip fast on a sustained overload — matching the thermal curve of standard induction motors.
This starter snaps directly onto 60 mm busbar systems — no DIN rail adapter needed. The mounting position is vertical only, and the clearance requirements are: 50 mm upward, 32 mm forward, 10 mm downward, and 10 mm at the side. Main circuit connections are screw-type terminals, so expect a standard screwdriver for termination — no special tooling required. The supplied contactor is a 3RT2015-1BB42 and the link module is 3RA1921-1DA00 — these are the matched components that make the reversing pair and interlock, so the assembly arrives as a functional unit, not loose parts.
Environmental limits and operating range
During operation the unit is rated for -20 to +60 °C ambient — adequate for most indoor panel environments, including non-conditioned electrical rooms in temperate climates. Storage and transport range is wider at -50 to +80 °C, which covers cold-weather shipping and hot warehouse storage without issue.
