Product details

The S3 footprint measures 146 mm high, 93 mm wide, and 139 mm deep — a compact envelope for a contactor rated at this insulation class.

Solid wire capacity: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded wire: 2x (10 to 50 mm²). For AWG, main contacts accept 2x (10 to 1/0). At 40 °C the minimum permissible conductor is 50 mm²; at 60 °C it drops to 35 mm² — derate for ambient heat.

Environmental and Protection

IP20 on the front with cover or box terminal; IP00 at the terminal itself — the contactor is intended for installation inside an enclosure that provides the overall IP rating. Pollution degree 3, suitable for industrial atmospheres with conductive pollution.

Frequently asked questions

What are the key ratings for this contactor?

Rated insulation voltage 1000 V, surge voltage resistance 6 kV, pollution degree 3. Operating temperature -25 to +60 °C. Main circuit terminals accept stranded wire up to 2x 50 mm².

What is the mounting method?

Screw and snap-on mounting onto 35 mm and 75 mm standard mounting rail. Side-by-side mounting is permitted.
