Form factor and mounting — 60 mm busbar, not DIN rail
The 3RA2220-4ED27-0AP0: This reversing starter is designed for snapping onto 60 mm busbar systems, not standard DIN rail — the fastening method and product design are specific to that busbar pitch. Dimensions are 260 mm height, 90 mm width, 155 mm depth — the depth is the dimension that governs clearance behind the panel door when mounted on the busbar. Mounting position is vertical only; clearance requirements are 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, and 0 mm backwards.
Motor switching capacity — AC-3 and Class 10
The supplied contactor is 3RT2027-1AP00 and the link module is 3RA2921-1AA00 — the assembly is factory-matched for coordination, not a field-build.
Environmental and terminal details
Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C — the wider storage band matters for spares held in unheated warehouses.
