Product details

The contactor is rated for 6 A at 24 VDC across the main contacts, with lower ratings at higher voltages: 2 A at 48 V and 60 V, 1 A at 110 V, and 0.9 A at 125 V. For AC motor duty, the mechanical life is 10 million operations typical, and the maximum switching frequency varies by duty class: 1000 cycles/h for AC-1 (resistive), 750 cycles/h for AC-2 and AC-3 (motor start/run), and 250 cycles/h for AC-4 (plugging/inching). The arcing time is 10 ms at 50 Hz.

The contactor accepts solid or stranded conductors from 1 to 10 mm² on the main circuit, with dual-wire capability for 2x (0.5 to 2.5 mm²). The spring-type terminals require no screwdriver torque, reducing wiring time.

Frequently asked questions

What is the depth of this contactor?

The depth is 144 mm, which is the dimension from the DIN rail mounting surface to the front of the contactor housing. This fits standard 200 mm deep enclosures with room for wiring.

What wire sizes does the spring terminal accept?

The spring-type terminals accept solid or stranded conductors from 1 to 10 mm² on the main circuit, and dual-wire connections of 2x (0.5 to 2.5 mm²).
