It carries four normally-open power poles and one built-in NO plus one NC auxiliary contact.
Power connections use bolted lugs or busbar rated for 185 mm² cross-section; control circuit terminals are push-in style accepting 0.2 to 2.5 mm² solid or stranded wire. Tightening torque for power terminals is 18 N·m. Mounting is plate-based, with a pitch of 35 mm between pole centers. The overall footprint is 143 mm wide by 255 mm tall by 193 mm deep, and the front face with shrouds achieves IP2X protection.
