Product details

The LC1K12103Q7 is a TeSys K three-pole contactor from Schneider Electric, rated for control applications. The 1 NO auxiliary contact is built in. Motor power ratings span 3 kW at 220-230 VAC up to 5.5 kW at 380-415 VAC and 440 VAC, and 4 kW at 480 VAC and 500-690 VAC, all at 50/60 Hz.

The 380-400 VAC coil is a direct line-voltage coil — no control transformer needed if the panel supply matches. Heat dissipation is 1.3 W, negligible for panel thermal budgeting. Flame retardance meets UL 94 V1 and NF F 16-101/102 requirements, which is standard for rail and industrial panel equipment.

The 3 NO power poles and single NO auxiliary fit within that envelope, leaving room for adjacent devices in a crowded panel.

Frequently asked questions

What is the closest alternative to LC1K12103Q7 in the TeSys family?

The TeSys K series has been superseded by the TeSys D range. A direct functional replacement would be a contactor like the LC1D12... with a 380-400 VAC coil, but verify the auxiliary contact configuration and mounting footprint — the D series is physically larger.

What are the key ratings of LC1K12103Q7?

Three-pole contactor, AC-3 rated 12 A at ≤440 V, with a 380-400 VAC coil. Motor power ranges from 3 kW (220-230 V) to 5.5 kW (380-440 V) and 4 kW at higher voltages up to 690 V. One normally open auxiliary contact is included.

What compliance documentation is available for LC1K12103Q7?

The contactor carries UL 94 V1 flame retardance rating and meets NF F 16-101/102 requirements. Standard Schneider documentation for the TeSys K series includes CE declaration and RoHS information.
