Busbar-mount starter — not DIN rail
The 3RA2110-4AH18-1AP0: This SIRIUS direct-on-line starter snaps onto 60 mm busbar systems, not a standard DIN rail — the fastening method is built into the housing, so you skip the adapter plate. Size S00 load feeder, 45 mm wide on the busbar, with a vertical mounting position — the 260 mm height and 155 mm depth mean it stands tall in the enclosure, so plan the gland plate clearance accordingly.
Pre-assembled contactor and link module
Trip Class 10 protection suits standard motor starting duty — no need to coordinate a separate overload relay; the link module handles the interconnection between the contactor and the busbar.
Main current circuit terminates with spring-loaded terminals — push the stripped conductor in, no screwdriver torque to check. Saves time on repetitive builds, but make sure the ferrule is the right length for the cage.
