Mounts standalone (stand-alone installation) on a vertical surface, rotatable ±135° and tiltable ±45° front-to-back, so it fits tight enclosures where the contactor is already fixed. The 70 mm width and 120 mm height are standard for the S3 frame; the 140 mm depth leaves clearance for the screw-type terminals on both the main and auxiliary circuits.
Main circuit terminals accept solid 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²) or stranded up to 70 mm². For auxiliary contacts, AWG 20–16 and 18–14. Coordination: with type 2 coordination requires a 200 A gG fuse upstream; type 1 coordination allows 250 A gG. That's the fuse sizing the panel builder needs to avoid welding the overload's N/C contacts on a bolted fault.
