Product details

The Schneider Electric LC1K12107D72 is a TeSys K three-pole contactor rated 12 A in AC-3 duty at ≤440 V, with a 42 V AC coil and one normally open auxiliary contact. The built-in bidirectional peak-limiting diode suppressor handles coil transients without external snubbing.

Motor power coverage

This contactor switches motor loads up to 5.5 kW at 380–415 V AC 50/60 Hz, 4 kW at 480 V and 500–600 V, and 3 kW at 220–230 V. The 660–690 V rating also carries 4 kW.

Heat dissipation is 1.3 W, so no special ventilation is required in a typical control panel.

Frequently asked questions

What are the key ratings for this contactor?

Rated operational current is 12 A in AC-3 at ≤440 V, with a 42 V AC coil. Motor power ranges from 3 kW at 220–230 V up to 5.5 kW at 380–415 V. The contactor has three NO main poles and one NO auxiliary contact.
