Product details

It carries 2 instantaneous normally-open contacts, rated 10 A at 24 V and 6 A at 230 V, with a mechanical endurance of 30 million cycles.

The 45 mm width and 72 mm depth fit standard S00 contactor spacing; the 57.5 mm height leaves clearance under typical enclosure depths.

Wiring and terminal capacity

Terminals accept solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². That covers most control-circuit wiring from 18 AWG to 12 AWG.

Shock resistance tested at 10g / 5 ms and 5g / 10 ms — sufficient for most industrial machinery, though not rated for continuous high-vibration applications like crushers.
