The LC1K06105FC7 is a 3-pole TeSys K contactor rated 6 A in AC-3 duty at ≤440 V, meaning it switches three-phase squirrel-cage motor loads up to that current — the AC-3 category covers starting and plugging, so the contactor is built for the inrush and break of motor starts, not just resistive heating. For a 400 V line, that 6 A AC-3 rating translates to roughly 2.2 kW motor power; at 480 V it supports 3 kW. The coil is 127 V AC, a common control voltage in North American 120 V class panels. One normally open auxiliary contact is integrated for feedback or interlocking. The part is also rated AC-4, covering reversing and inching duty where the contactor breaks stalled-rotor current — more severe than AC-3. If the application involves frequent plugging or jogging, the AC-4 rating confirms the contactor is designed for that wear profile, not just occasional motor starts.

Frequently asked questions
What is the closest alternative to LC1K06105FC7 in the TeSys K family?
Within the TeSys K range, a direct alternative would be a contactor with the same pole count, same AC-3 current rating, and same coil voltage. The LC1K06105FC7 uses a 127 V AC coil; any sibling with a different coil voltage (e.g., 24 V AC, 230 V AC) would not be a drop-in replacement without changing the control circuit. The physical footprint and auxiliary contact configuration are consistent across the LC1K frame size.
What compliance documentation is available for this part?
The part carries UL 94 V1 flame retardance rating and conforms to NF F 16-101 and NF F 16-102 for fire behavior in railway applications. As a Schneider Electric TeSys K product, it is typically supported by a full declaration of conformity covering IEC/EN 60947-4-1, CE marking, and RoHS/REACH compliance documentation available on request.
