Product details

The AC-1 resistive rating supports 1,200 operations per hour; AC-3 and AC-4 rates are 1,000/h and 250/h respectively. Auxiliary contacts are rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — enough for pilot-duty signaling in the same panel.

The 55 mm width and 115 mm depth leave room for side-by-side mounting (yes, supported) — useful when packing multiple contactors in a motor control center row. Screw terminals accept 2x (0.5...1.5 mm²) solid or 2x (0.75...25 mm²) stranded. The main circuit also takes 2x (0.75...16 mm²) solid/stranded.

Environmental and lifecycle

The front carries IP20 (finger-safe), the terminal area is IP00 (open).
