Product details

It's a 3-pole unit rated for AC-3 duty at 12 A up to 440 V, with a 110 V AC coil. The AC-3 rating means it's sized for starting and stopping squirrel-cage motors under load — the real-world spec that governs fit for a motor control circuit, not the higher AC-1 resistive rating.

This part is listed as obsolete by the manufacturer. There is no official successor order code, so a direct drop-in replacement isn't confirmed.

Fit and integration notes

The contactor measures 90 mm wide by 58 mm high by 57 mm deep, with IP20 finger protection per VDE 0106.

The 110 V AC coil is standard for this voltage class.

Frequently asked questions

What are the key ratings for this reversing contactor?

It is a 3-pole reversing contactor rated AC-3 at 12 A up to 440 V, with a 110 V AC coil. The AC-1 and AC-4 utilisation categories also apply, but AC-3 is the motor-duty rating that governs fit.

What physical size is the LC8K12105F7?

It measures 90 mm wide, 58 mm high, and 57 mm deep, with IP20 finger protection. Ambient operating range is -25 to 50 °C.
