The LC1K06106R7 is a 3-pole TeSys K contactor rated 6 A in AC-3 duty at ≤440 V, meaning it switches three-phase motor loads up to that current — the AC-3 category covers starting and stopping squirrel-cage motors under load. Motor power equivalents are 1.5 kW at 220–230 V, 2.2 kW at 380–415 V, and 3 kW at 440–690 V, so the same contactor covers a 400 V class motor in Europe and a 480 V motor in North America without a frame size change. The 440 V AC coil draws its control voltage from the line side or a separate control transformer; verify the coil matches your control circuit voltage before panel wiring. The contactor carries AC-4 ratings as well, which covers plugging and inching duty where the motor is reversed or jogged under load — a harder switching condition that derates the current. For pure AC-4 use, expect to downrate from the 6 A AC-3 figure. The 1 NO auxiliary contact is built in; additional aux blocks can be added on the side for feedback or interlocking.

Frequently asked questions
What motor sizes does the LC1K06106R7 cover?
It covers 1.5 kW at 220–230 V AC, 2.2 kW at 380–415 V AC, and 3 kW at 440–690 V AC, all at 50/60 Hz. This means one contactor handles a 2.2 kW European 400 V motor or a 3 kW North American 480 V motor.
What compliance documentation is available for this contactor?
The contactor carries UL 94 V1 flame retardance and NF F 16-101/102 Requirement 2 for railway fire safety. RoHS and REACH declarations are available from the manufacturer.
What is the closest alternative in the TeSys K family?
The LC1K0610 is the same frame with a 6 A AC-3 rating but a different coil voltage. If your control circuit is 440 V AC, this LC1K06106R7 is the correct coil variant. For a 24 V DC coil or 230 V AC coil, the order code suffix changes — the base contactor body and aux contact count are identical.
