Product details

29 A AC-3 reversing starter for 60 mm busbar systems

The 3RA2220-4EH27-0BB4: The supplied contactor is a 3RT2027-2BB40 and the link module is 3RA2921-2AA00, so the assembly is pre-coordinated from the factory.

Mounting and clearance for panel integration

Dimensions are 260 mm high, 90 mm wide, 165 mm deep. Mounting position is vertical only. Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, and 0 mm backwards — so the back can sit flush against the panel backplane. This matters when laying out a dense busbar-fed section.
