The 3RA2150-4PA35-0NB3: Mounts via screw and snap-on to two 35 mm DIN rails; the 150 mm depth × 55 mm width × 274 mm height footprint fits standard panel layouts with 50 mm clearance above and 32 mm forward. Main circuit connections are screw-type terminals — no special tooling needed for field wiring, and the supplied contactor (3RT2035-1NB30) and link module (3RA2931-1AA00) are pre-assembled as a single orderable unit.
