The Schneider Electric LC2K16105Q7 is a TeSys K reversing contactor — a 3-pole unit rated 16 A in AC-3 duty at ≤440 V, with a 380...400 V AC coil and one normally open auxiliary contact. It arrives preassembled with the reversing power busbar, so the mechanical and electrical interlock is already integrated. This is the part you pull when a motor-forward/reverse pair needs a compact, panel-ready package. Rated for motor control in AC-3 (starting/running squirrel-cage motors) and AC-4 (plugging, inching) utilisation categories. The 16 A AC-3 rating governs the real-world motor size it can switch — roughly a 7.5 kW motor at 400 V depending on the duty cycle, though the exact sizing depends on the load profile and ambient conditions. The operating range is -25 to 50 °C ambient, with storage down to -50 °C.
Lifecycle status and sourcing reality
A parametric replacement would need to match the 3-pole reversing contactor footprint, the 16 A AC-3 rating, and the 380-400 V AC coil voltage — but the physical mounting and busbar arrangement may differ. Any cross-reference should be verified against the panel layout and wiring scheme.
The contactor measures 90 mm wide by 58 mm high by 57 mm deep. Snaps onto a DIN rail per standard practice. The preassembled reversing busbar saves installation time — no separate busbar kit or interlock wiring needed between the two contactor halves. Flame retardance meets V1 per UL 94 and the more stringent NF F 16-101 / 16-102 railway standards. Protective treatment is TC per IEC 60068 and DIN 50016, meaning the part is treated against corrosion in tropical climates. Shock and vibration ratings are specified per IEC 60068-2-27 and IEC 60068-2-6 — the contactor holds closed through 10 Gn on the Y and Z axes, and 4 Gn vibration closed across 5-300 Hz.
