The LC1K16106N7 is a TeSys K three-pole contactor from Schneider Electric, rated 16 A in AC-3 utilisation category at ≤440 V, with a single normally-open auxiliary contact and a 400…415 V AC coil. It is now listed as obsolete.
The AC-3 rating (16 A at ≤440 V) governs motor switching duty — this contactor is sized for a 7.5 kW motor on a 380…415 V supply, or 5.5 kW at 440 V, or 4 kW at 480 V and up to 690 V. The AC-1 rating covers resistive loads at the same current level. The 400…415 V AC coil is specific to that voltage band; it will not pull in reliably on a 480 V control circuit without a dropping resistor or transformer.
Integration notes
The contactor dissipates 1.3 W at rated load — negligible for most enclosures, but worth checking if it sits next to solid-state devices in a sealed cabinet. Flame retardance is V1 per UL 94, which is standard for this class. The 3 NO main poles and 1 NO auxiliary are fixed; no field-convertible contact arrangement.
