Product details

The coil accepts 20-33 V AC/DC. Inrush current peaks at 3 A.

The auxiliary contact block (attachable up to 2 units) carries rated currents that vary by voltage: 10 A at 24 V AC, 10 A at 230 V AC, and 3 A at 400 V AC. For DC switching, it handles 2 A at 48 V, 6 A at 60 V, and 1 A at 110 V. These ratings define the maximum continuous current the auxiliary contacts can break — useful for signaling to a PLC or holding in a control relay.

The contactor accepts solid or stranded conductors: 2x 0.5-1.5 mm² and 2x 0.75-2.5 mm² per terminal. The screw-type terminals are straightforward for panel wiring — no special tooling needed beyond a standard screwdriver. That 6 mm side gap is tight — ensure adjacent devices or wiring ducts don't crowd the arc-chamber vents.

Frequently asked questions

What are the mounting dimensions and clearances?

The contactor measures 114 mm high, 75 mm wide, and 130 mm deep. Required clearances: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side.
