Termination is ring cable lug — not spring-cage or screw-clamp. That means you need crimp lugs on the power wiring, which is standard for higher-current solid-state contactors but worth flagging if your panel shop is used to push-in terminals on smaller contactors. Plan for lug crimping tooling and a bit more wire-bending space in the enclosure. Packaged as a single piece in a 105 x 50 x 125 mm box. No DIN-rail adapter mentioned in the spec — verify mounting method against your enclosure layout before committing the BOM line.
