The LC1K09105V7TQ is a TeSys K three-pole contactor from Schneider Electric, rated 9 A in AC-3 utilisation category at ≤440 V, with a 400 V AC coil and one normally open auxiliary contact. It's designed for control applications — switching motor loads, resistive heaters, or other inductive circuits in panel builds. The contactor carries motor power ratings across common supply voltages: 2.2 kW at 220–230 V AC, 4 kW at 380–415 V, 4 kW at 440 V, 4 kW at 480 V, and 4 kW at 500–600 V and 660–690 V, all at 50/60 Hz.
Sourcing reality — obsolete, sourced to order
The LC1K09105V7TQ is obsolete. No official successor order code from Schneider is available. For a drop-in, verify pinout and footprint against your panel layout.
The contactor also carries AC-4 (inching/plugging) and AC-1 (resistive) utilisation categories, so it can handle duty-cycle applications beyond simple on/off motor starting. Short-time withstand current (Icw) is specified for the power circuit: 90 A for 1 s, 85 A for 5 s, 80 A for 10 s, down to 20 A for ≥15 min at 50 °C. This tells you the contactor can survive fault currents long enough for an upstream protective device to clear — useful when coordinating with a motor circuit breaker or fuse. Flame retardance meets V1 per UL 94, plus Requirement 2 per NF F 16-101 and NF F 16-102 — relevant for rail or transit applications where fire-smoke-toxicity standards apply.
Physical integration
Pole composition is 3 NO (three normally open main poles), with one NO auxiliary contact built in. The coil is 400 V AC — verify your control circuit voltage matches.
