It is rated for AC-3 duty at 18.5 kW on a 500 V, 50 Hz supply, and also carries ratings of 15 kW at 400 V AC-2 and 10 kW at 690 V — so it covers the common European voltage tiers for three-phase induction motors.
The AC-4 rating of 29 A at 400 V covers plugging and inching duty, which is more demanding on the contacts.
The main circuit uses screw-type terminals; solid wire up to 2x (0.25... 2.5 mm²) and stranded up to 2x (0.75... 25 mm²) are accepted. At 40 °C the minimum permissible conductor cross-section is 16 mm², which is worth noting when sizing the feed. The overall dimensions are 112 mm high, 75 mm wide, and 115 mm deep — a compact S2 footprint that fits a standard 200 mm deep enclosure.
Regulatory and compliance
The contactor carries a substance prohibitance date of 05/01/2012, which aligns with RoHS compliance (the EU RoHS directive effective date). It also meets the degree of pollution 3 per IEC 60947-1, meaning it is certified for industrial atmospheres with non-conductive dust.
