5 A AC-3 reversing starter — what the rating means in the panel
The 3RA2220-1FF24-0BB4: The 24 VDC coil keeps the control circuit isolated from the power side; the supplied contactor (3RT2024-2BB40) and link module (3RA2921-2AA00) are pre-assembled, so the reversing starter arrives as a single unit ready to wire.
Mounting and wiring — DIN rail footprint with spring terminals
Mounts on 35 mm DIN rail via an adapter that accepts both screw and snap-on fastening; the mounting position is vertical. Dimensions are 130 mm deep by 90 mm wide by 269 mm high. Clearance requirements: 50 mm upward, 32 mm forward, 10 mm downward, and 10 mm at the side — budget these into the panel layout for airflow and wiring access.
