The Schneider Electric LC2K16105P72 is a TeSys K reversing contactor — a 3-pole, 3 NO power pole unit rated for AC-3 and AC-4 duty at 16 A up to 440 V, with a 230 V AC coil and one normally open auxiliary contact. The 16 A AC-3 figure means it handles a 3-phase motor drawing roughly 16 A full-load — think a 7.5 kW motor at 400 V — without welding the main poles on start. The unit ships preassembled with the reversing power busbar, so you don't need to source a separate mechanical interlock or busbar kit. That saves panel-build time and avoids the risk of a misaligned interlock that could let both contactors close simultaneously — a direct phase-to-phase short. IP20 finger-safe terminals (VDE 0106) mean it's protected against accidental contact inside an enclosure, but not against dust or moisture ingress — mount it in a cabinet rated for the environment.
For consignment or VMI programs, the predictable demand pattern and standardized form factor make it a good candidate for auto-replenishment — the bin's running low signal triggers a release without manual PO intervention.
Mechanical endurance and shock handling
The contactor is tested to withstand 10 Gn shocks on the Y and Z axes (contactor closed) and 15 Gn on the same axes when closed — that's rail or marine-grade vibration resistance. Vibration tolerance is 4 Gn closed, 2 Gn open across 5-300 Hz per IEC 60068-2-6. For a reversing contactor on a conveyor or crane, this means it won't drop out under mechanical shock that would bounce a lesser contactor open.
