The LP4K12016BW3 is a TeSys K 3-pole contactor from Schneider Electric, rated for AC-3 duty at 12 A up to 440 V with a 24 V DC coil. It carries one normally closed auxiliary contact and includes a built-in bidirectional peak limiting diode suppressor across the coil — no external flyback diode needed on the control wiring.
Integration note
The built-in diode suppressor on the 24 V DC coil means the control wiring needs no external snubber — verify polarity before energizing. The 3 NO main poles and 1 NC auxiliary contact are labeled on the nameplate; auxiliary wiring shares the same terminal pitch as the TeSys K block range.
