Form factor and mounting — snaps onto 60 mm busbars
The 3RA2220-1GH24-0AP0: This reversing starter is designed for snapping onto 60 mm busbar systems, not a standard DIN rail — the fastening method is specific to the busbar adapter included (8US1251-5NT11). Dimensions are 165 mm deep, 90 mm wide, and 260 mm high; mounting position is vertical, with 50 mm clearance upward, 32 mm forward, and 10 mm at the side and downward.
Motor protection and wiring — Class 10, spring terminals
Rated power at 400 V is 2.2 kW; the main circuit uses spring-loaded terminals for fast, vibration-resistant wiring without retorquing. The supplied contactor is a 3RT2024-2AP00, and the link module is 3RA2921-2AA00 — these are factory-matched, so the reversing interlock and overload coordination are pre-validated.
