Rated insulation voltage is 1000 V, and the AC-3e maximum operational voltage is also 1000 V — this covers 400 V and 690 V distribution common in European and Asian plants. The contactor carries a varistor surge suppressor built in, so you can skip external snubber wiring on most inductive loads.
Fastening is screw fixing, not DIN-rail snap-on — plan for a drilled backplate or mounting rail. The contactor supports side-by-side mounting with no derating gap, which saves panel width when stacking multiple units. Dimensions are 210 mm height, 145 mm width, 202 mm depth — the depth is the main constraint for shallow enclosures.
Terminals and ratings
Main current circuit uses screw-type terminals, sized for conductors up to 185 mm² at both 40 °C and 60 °C ambient. Switching frequency: 2000 cycles per hour for both AC and DC operation; AC-1 max 800 cycles/h, AC-3 max 700 cycles/h, AC-4 max 130 cycles/h.
