The 3RA2225-1HB24-0BB4: Rated for reversing duty — two contactors interlocked mechanically and electrically — so it handles forward/reverse control of a three-phase motor without external interlocking wiring.
DIN rail footprint and panel fit
Snap-on fastening on 35 mm standard rail, vertical mounting position. Dimensions: 90 mm wide, 130 mm deep, 265 mm tall — the S0 frame keeps the width tight for multi-starter panels. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, 0 mm backwards. The zero rear clearance means it can sit flush against a back panel or busbar support.
Rated power and trip class
Rated motor power at 400 V is 3 000 W (4 hp), at 500 V is 4 000 W (5.4 hp). At 480 V the rated current is 7.92 A; at 600 V it is 6.33 A. The maximum AC-3 switching voltage is 690 V. Control voltage is 24 V — the coil is designed for 24 VAC/DC, common in PLC-driven panels. The supplied contactor is 3RT2024-1BB40; the link module is 3RA2921-1BA00; the busbar adapter is 3RA2922-1AA00.
Environmental and compliance
Operating temperature range -20 to +60 °C; storage -50 to +80 °C; transport -55 to +80 °C. Degree of pollution 3 (conductive pollution typical in industrial enclosures). Substance prohibitance date 03/01/2017 — the starter complies with RoHS and REACH substance restrictions effective from that date.
