Product details

DIN-rail footprint and panel fit

The 3RA2120-1JE24-0AP0: Vertical mounting position is specified; clearance requirements are 50 mm upward, 20 mm forward, and 10 mm downward for airflow and wiring access.

Factory-matched contactor and link module

The starter ships with the 3RT2024-2AP00 contactor and 3RA2921-2AA00 link module pre-assembled — no separate ordering or wiring of the contactor-to-overload bridge. The S0 circuit-breaker size matches the feeder frame, keeping the BOM consistent across the panel.
