The AC-3 rating of 9 A and 4 kW at 400 V defines its motor-switching capability: it handles squirrel-cage motors during starting and running, where the inrush can be 5–7× the rated current. The Size S00 footprint (45 mm wide, 57.5 mm high, 72 mm deep) snaps onto a 35 mm DIN rail per EN 50022, with 6 mm side spacing required to grounded parts. The single NO auxiliary contact is built in; no add-on block is included.
Screw terminals on both main and auxiliary circuits accept 2× (0.5…1.5 mm²) solid or 2× (0.75…2.5 mm²) stranded, up to 2× (0.75…4 mm²) maximum. For AWG, that's 2× (20…16) solid, 2× (18…14) stranded, or 1× 12. The contactor mounts side-by-side without derating, provided the 6 mm air gap to grounded parts is maintained.
Mechanical and electrical endurance
Short-circuit protection for the main circuit requires a gL/gG fuse: 20 A for Type 2 coordination, 35 A for Type 1.
