The 3RA2120-1GD24-0AP6: Rated 690 V maximum at AC-3 duty — this covers 400 V, 480 V, and 600 V motor circuits without derating the switching capacity. The direct-starter design integrates the contactor and overload into one S0-size package — 45 mm wide, 155 mm deep, 260 mm tall — saving panel width compared to separate components. Mounting is vertical only, with fastening by snapping onto 60 mm busbar systems.
What ships in the box — supplied sub-assemblies
The unit ships as a factory-assembled set: the supplied contactor is the 3RT2024-1AP60, the supplied link module is the 3RA2921-1AA00, and the supplied busbar adapter is the 8US1251-5NT10. This means the motor starter arrives ready to snap onto the busbar system and wire — no separate ordering of contactor, overload, or busbar adapter for the S0 feeder size.
Environmental limits for panel placement
The degree of pollution is 3, which means the device is rated for conductive pollution environments typical in industrial control panels without sealed enclosures. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, 0 mm backwards.
