Product details

It mounts via screw and snap-on onto a 35 mm DIN rail per DIN EN 50022, fitting into a standard panel layout with a 45 mm width and 85 mm height, and a depth of 91 mm. Rated for 400 V at 50 Hz and 400 to 440 V at 60 Hz, this contactor delivers 4.5 kW at 500 V and 5.5 kW at 690 V. The 24 V DC coil draws 10 A, and the AC-4 rating at 400 V is 8.5 A — the value that governs switching of motor loads under inrush and plugging conditions, not the steady-state AC-1 figure.

Coordination and wiring

Main circuit terminals accept screw-type connections: solid conductors 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²); stranded conductors 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), 1x 8.

Frequently asked questions

What are the key ratings for this contactor?

Rated 400 V at 50 Hz, 400 to 440 V at 60 Hz. Delivers 4.5 kW at 500 V and 5.5 kW at 690 V. The AC-4 rating at 400 V is 8.5 A, which governs motor switching under inrush. Coil draws 10 A at 24 V DC. Mechanical life is 10,000,000 cycles.

What is the depth of this contactor?

The depth is 91 mm, with a width of 45 mm and height of 85 mm.

What wire sizes does the main circuit accept?

Solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded: 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG: 2x (16 to 12), 2x (14 to 10), 1x 8.

What fusing is required for type 2 coordination?

For type 2 coordination, use a gL/gG fuse rated 25 A. For type 1 coordination, use a gL/gG fuse rated 63 A.
