The main current circuit uses screw-type terminals, rated for solid conductors up to 2x 4 mm² and stranded up to 2x 50 mm² — a range that covers most motor branch feeds up to the contactor's rated power. Per the datasheet, the operating temperature span is -25 to +60 °C, with storage down to -55 °C; pollution degree 3 means it tolerates conductive dust in typical factory environments.
Footprint is 70 mm wide by 146 mm tall by 139 mm deep. The IP20 rating on the front with the cover or box terminal installed means the live parts are finger-safe inside the enclosure; the terminal itself is IP00, so the panel door must be closed before energizing.
