Product details

The Schneider LC7K12107M7 is a TeSys K 3-pole contactor rated for AC-3 motor switching at 12 A up to 440 V, with a 220...230 V AC coil and one normally-open auxiliary contact. The utilisation categories cover AC-1 (resistive), AC-3 (squirrel-cage motor starting), and AC-4 (plugging/reversing).

Motor power map and current ratings

This contactor handles 5.5 kW at 380...415 V AC and at 440 V AC, 4 kW at 480 V AC and at 500...600 V AC and at 660...690 V AC, and 3 kW at 220...230 V AC — all at 50/60 Hz. The rated operational current [Ie] is 20 A, but the AC-3 motor switching rating is 12 A (at ≤440 V). The short-time withstand current [Icw] for the power circuit is 115 A for 1 s at 50 °C, stepping down to 55 A for 1 minute and 25 A for ≥15 minutes — important for coordination studies when sizing upstream protection.

Physical integration and panel fit

Heat dissipation is 3 W, so no special ventilation in a typical panel. Flame retardance meets UL 94 V1 and NF F 16-101/102 class 2, which matters for rail and transit applications where fire-smoke-toxicity requirements apply.

Sourcing reality — obsolete part

Obsolete per the manufacturer. Sourcing is through independent channels — we quote against an RFQ on a per-lot basis.

Frequently asked questions

What is the closest alternative to this contactor?

No official successor is named in the record. A current-production TeSys K or TeSys Deca contactor with a 220...230 V AC coil and matching pole/auxiliary count is the functional starting point, but the auxiliary contact arrangement and physical footprint need checking against your panel layout.

What are the key motor power ratings?

5.5 kW at 380...415 V AC and 440 V AC; 4 kW at 480 V, 500...600 V, and 660...690 V AC; 3 kW at 220...230 V AC. All at 50/60 Hz.

What is the physical size?

45 mm wide, 58 mm high, 57 mm deep — a standard DIN-rail mount that fits 45 mm modular enclosure slots.
