Product details

The coil termination uses screw-type terminals, a common preference for field wiring where ring or fork lugs are standard. It measures 45 mm wide, 58 mm deep, and 117 mm high, making it a compact fit for DIN-rail cabinets. Rated for AC-1 resistive loads at up to 1 000 1/h and AC-3 motor switching at 750 1/h. Mechanical life 10 000 000.

Side clearance of 6 mm and top/bottom clearance of 10 mm are required for arcing and ventilation. Forwards/upwards/downwards spacing of 10 mm ensures safe arc quenching.

Frequently asked questions

What are the key dimensions of this contactor?

Width 45 mm, height 58 mm, depth 117 mm. It is size S00.

What conductor cross-sections does the main circuit accept?

Solid or stranded wire from 0.5 to 4 mm². Two conductors per terminal can be doubled up: 2×(0.5–1.5 mm²), 2×(0.75–2.5 mm²), or 2×4 mm².
