Reversing starter for 60 mm busbar panels
The 3RA2210-0KS15-2BB4 is a SIRIUS reversing starter in size S00, designed specifically for snapping onto 60 mm busbar systems. It ships with the supplied contactor (3RT2015-2BB42), link module (3RA2911-2AA00), and busbar adapter (8US1251-5DS11) — a complete reversing assembly, not a bare contactor. The thermal bimetallic overload release is set to Class 10 trip curve — this coordinates with standard motor start profiles where the rotor is up to speed within 10 seconds. Main circuit connections use spring-loaded terminals — no screw torque to verify, no periodic retightening. The mounting position is vertical only, with 50 mm clearance upward and 32 mm forward for arc flash and ventilation.
Panel layout and clearance envelope
Dimensions: 155 mm deep, 90 mm wide, 230 mm high. Side clearance is 10 mm on each side; zero clearance required behind the unit. Downward clearance is 10 mm. These clearances must be maintained inside the enclosure to avoid heat buildup and meet the -20 to +60 °C operating range. Storage and transport temperature range is -50 to +80 °C, which covers most unheated warehouse and trucking conditions. The RoHS compliance date is 10/01/2009 — the starter meets the original RoHS directive; REACH and UKCA documentation is typically bundled with the unit or available per request.
Sourcing and compliance posture
This is a standard catalog item from the SIRIUS series, not a custom or project-specific variant. The reversing starter carries no PROFIsafe or PROFINET IO protocol support — it is a standalone electromechanical assembly, not a fieldbus node. For safety-related applications, a separate safety relay or F-module must handle the stop circuit.
