Form factor and mounting — snaps onto a 60 mm busbar
The 3RA2225-0JD23-0BB4 is a SIRIUS non-fused reversing motor starter in the S0 feeder size, meaning it integrates the contactor, overload relay, and reversing interlock in a single package that snaps onto a 60 mm busbar system. Its envelope is 260 mm high, 90 mm wide, and 165 mm deep — the depth is the dimension to check if the panel has a shallow backpan or a rear-mounted bus. Mounting position is vertical only; the unit needs 30 mm clearance upward, 10 mm forward, 10 mm downward, and 9 mm at the side for cooling and wiring access.
What comes in the box — supplied sub-assemblies
This reversing starter ships as a complete assembly: the supplied contactor is a 3RT2023-1BB40, the link module is 3RA2921-1BA00, the circuit-breaker is a 3RV2011-0JA15 (size S00), the busbar adapter is 8US1251-5NT10, and the RS assembly kit is 3RA2923-1DB1. The overload release is thermal bimetallic (Class 10 trip curve), and the short-circuit trip is magnetic — no electronic adjustments, just a straight electromechanical design that is field-proven in industrial motor protection.
Motor power coverage and wiring
Rated motor power at 400 V is 250 W, at 500 V is 370 W, at 690 V is 550 W, and at 575/600 V is 0.5 hp — these are the AC-3 switching limits for the reversing contactor set. Main contact wiring accepts 1 to 10 mm² stranded or 2x (2.5 to 6 mm²); AWG equivalents are 2x (16 to 12) or 2x (14 to 8).
Environmental limits and compliance
Operating temperature range is -20 to +60 °C; storage range is -50 to +80 °C; transport range is -55 to +80 °C — the wider storage/transport limits matter for warehousing and shipping in unheated containers. Pollution degree 3 (conductive pollution or dry non-conductive pollution that becomes conductive due to condensation) — typical for control panels in industrial environments not sealed to IP54. RoHS compliance date is 03/01/2017; the part carries the substance prohibitance marking for the EU RoHS directive.
