S00 reversing starter — snap-on busbar mount
The 3RA2210-1HH15-2BB4: It ships with the 3RT2015-2BB42 contactor and the 3RA2911-2AA00 link module already integrated — one order code, one assembly, no separate sourcing for the contactor and mechanical interlock. The enclosure dimensions are 155 mm deep, 90 mm wide, and 260 mm tall. It snaps directly onto 60 mm busbar systems — no DIN rail adapter needed for that busbar pitch. Mounting position is vertical only.
AC-3 duty and terminal wiring
At 400 V AC-3, the rated operational current is 7 A. That's the motor-switching current for standard squirrel-cage motors — start, stop, and reversing under load. The maximum AC-3 voltage is 690 V. Horsepower ratings span from 0.25 hp at 110/120 V up to 5 hp at 575/600 V. Main circuit connections use spring-loaded terminals — no screw torque to verify, no loosening under vibration. The supplied contactor is the 3RT2015-2BB42, and the link module is the 3RA2911-2AA00. If you're replacing a failed reversing starter in the field, this assembly drops in as a complete unit.
Clearance and ambient limits
Minimum clearances around the unit: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the sides, and 0 mm backwards. The backwards clearance being zero means it can sit flush against the back panel or busbar support. Operating ambient range is -20 to +60 °C; storage and transport range is -50 to +80 °C.
