The Schneider Electric TeSys K LC2K09103D7 is a 3-pole reversing contactor rated for AC-3 duty at 9 A up to 440 V, with a 42 V AC coil. Rated for AC-1 (resistive), AC-3 (squirrel-cage motor starting), and AC-4 (plugging/inching) utilisation categories, it covers the full range of reversing motor applications — conveyors, hoists, pumps, and any load that needs direction reversal under load. The IP20 finger-safe enclosure (per VDE 0106) means it's suitable for installation inside a control cabinet where personnel may reach near live parts during maintenance — standard for panel-mounted contactors.
Sourcing and lifecycle — active production, no obsolescence concern
For a maintenance-spares buyer holding a legacy TeSys K install, this is a direct drop-in replacement that matches the original form factor and coil voltage. One in the cabinet as a critical spare keeps a reversing motor circuit covered before it fails.
The 9 A AC-3 rating at <= 440 V governs motor switching — it handles a 3-phase induction motor up to roughly 4 kW at 400 V. The AC-1 resistive rating carries a higher current, but for motor loads the AC-3 figure is the one that decides fit. Flame retardance rated V1 per UL 94 and compliant with NF F 16-101 and NF F 16-102 — relevant for rail and transit applications where fire-smoke-toxicity requirements are stricter than general industrial. The preassembled reversing busbar adds about 30 mm to the overall width compared to a single contactor, so account for that in your panel fill factor.
