Product details

The coil terminates with spring-type terminals, while the main and auxiliary contacts accept solid conductors from 0.5 to 2.5 mm² (2x) and stranded conductors from 1 to 10 mm².

The integrated auxiliary switch carries rated values across DC voltage levels: 10 A at 24 V, 2 A at 48 V, 6 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 10 A at 230 V. At higher AC voltages it is rated 3 A at 400 V, 2 A at 500 V, 0.1 A at 600 V, and 1 A at 690 V. These ratings define the maximum continuous current the auxiliary contacts can handle at each voltage — critical when feeding PLC inputs, indicator lamps, or interposing relays in the same panel.

Mounting and Environmental Flexibility

Mechanical endurance is rated at 10,000,000 operating cycles typical, and the contactor's arcing time is 10 to 10 ms. Operating times at DC are 15 to 18 ms for both pickup and dropout.

Frequently asked questions

What is the coil voltage and type?

The coil is rated 24 V DC.

What conductor sizes does it accept?

Solid conductors: 2x (0.5 to 2.5 mm²). Stranded conductors: 1 to 10 mm².
