Product details

It carries 3 NO power poles and is rated for three utilisation categories: AC-1 (resistive loads), AC-3 (squirrel-cage motors), and AC-4 (plugging/inching duty). At ≤440 V AC, the AC-3 motor switching rating is 12 A — the figure that governs the motor size it can handle in forward-reverse duty.

Rated operational voltage on the power circuit is 690 V AC 50/60 Hz, so it can sit on a 400 V or 480 V line without issue. The 24 V AC coil is standard for panel control transformers — verify your control transformer VA is adequate for the coil inrush if multiple contactors pull in simultaneously. AC-4 duty (plugging) will derate further. IP20 finger-safe terminals (VDE 0106) mean it needs enclosure protection against dust and liquid.

It's a compact reversing contactor — the preassembled busbar saves panel space vs wiring two separate contactors with an interlock. Mounts on DIN rail or with screws. The 3 NO configuration with no NC auxiliary means you'll need to add a separate auxiliary contact block if your control circuit requires a feedback signal or electrical interlock.

Flame retardance rated V1 per UL 94, and compliant with NF F 16-101 and NF F 16-102 for rail applications. Protective treatment conforms to IEC 60068 and DIN 50016. Mechanical robustness: tested for shock and vibration per IEC 60068-2-27 and IEC 60068-2-6 — contactor closed withstands 10-15 Gn shocks depending on axis.

Frequently asked questions

What is the AC-3 rating and what motor can it switch?

The AC-3 rating is 12 A at ≤440 V AC, which corresponds to switching a motor up to roughly 5.5 kW at 400 V (standard IEC motor sizing). Match the motor FLA to this figure for reversing duty.

Does this contactor come with the reversing busbar?

Yes, the LC8K1210B7 is described as preassembled with a reversing power busbar, so it is ready for forward-reverse wiring out of the box.

What approvals does this part carry?

It carries V1 flame retardance per UL 94, complies with NF F 16-101 and NF F 16-102 for rail, and its protective treatment conforms to IEC 60068 and DIN 50016. IP20 per VDE 0106.
