The Schneider Electric LC2K1610B72 is a TeSys K reversing contactor — a 3-pole unit rated for 16 A in AC-3 duty at up to 440 V, with a 24 V AC coil and one normally open auxiliary contact. It comes preassembled with the reversing power busbar, so you don't have to wire the mechanical interlock and bus links yourself. That saves panel-build time and reduces the chance of a wiring error that could let both contactors pull in at once. Rated operational voltage on the power circuit goes to 690 V AC 50/60 Hz, but the AC-3 motor-switching rating is what governs real-world selection: 16 A at ≤440 V. AC-4 rating (inching/plugging duty) is also listed, so it handles the reversing cycles that generate higher electrical wear on the contacts. The 24 V AC coil draws from a control transformer — common for panel layouts where 24 VAC control is already on the DIN rail.

Frequently asked questions
What is the AC-3 motor rating for this contactor?
16 A at ≤440 V AC in AC-3 duty. That's the rating that governs motor switching — it tells you the contactor can handle a motor full-load current up to 16 A within that voltage class.
Does this come with the reversing busbar pre-installed?
Yes, the LC2K1610B72 is described as preassembled with the reversing power busbar. That means the mechanical interlock and power bus links are already in place between the two contactor halves — you wire the coil and load connections only.
What approvals and compliance documentation are available?
Flame retardance meets UL 94 V1 and NF F 16-101/102. IP20 per VDE 0106. Protective treatment conforms to IEC 60068 and DIN 50016. Vibration and shock tested per IEC 60068-2-27 and IEC 60068-2-6. The part carries the TeSys K range designation under Schneider Electric's catalog.
