Product details

Panel fit and mounting constraints

The 3RA2120-1FA24-0AP0: Mounts vertically on 35 mm DIN rail via screw and snap-on fastening, or can be screw-mounted directly to a backplate. The unit is 45 mm wide, 193 mm tall, and 97 mm deep — plan for the 50 mm upwards and 20 mm side clearances for wiring and heat dissipation. Main circuit connections use screw-type terminals; the supplied contactor is 3RT2024-1AP00 and the link module is 3RA2921-1AA00, so the assembly is pre-coordinated for thermal and magnetic protection.
