Product details

The 24 VDC coil pulls in at 0.8 of rated voltage and holds reliably; the integrated auxiliary switch (1 NO + 1 NC, rated 10 A at 24 V) eliminates the need for a separate add-on block for basic status feedback. Rated for AC-3 duty at 1000 operating cycles per hour, this contactor handles the inrush and breaking of squirrel-cage motors within its frame rating. The screw-type main terminals accept solid or stranded conductors from 1 to 10 mm² — typical for a 4–7.5 kW motor circuit at 400 V.

Clearances and mounting

Minimum clearance to adjacent components: 10 mm upward, downward, and forward; 6 mm at the sides. Depth is 107 mm, height 85 mm — factor these into gland-plate clearance and door swing.

The built-in auxiliary switch is rated for DC switching at various voltages: 10 A at 24 V, 2 A at 48 V or 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. At 400 V AC, the auxiliary contact handles 3 A.
