The LP4K12015FW3 is a 3-pole TeSys K contactor rated 12 A in AC-3 duty at ≤440 V, with a 110 V DC coil. It carries a built-in bidirectional peak limiting diode suppressor across the coil, which simplifies panel wiring — no external flyback diode needed. Rated operational current is 12 A in AC-3 (motor switching), 16 A in AC-1 (resistive), and 20 A in AC-4 (frequent inching/plugging). The 3 NO main poles handle 3-phase loads; the 1 NC auxiliary contact is built in. Coil hold-in power is 1.8 W at 20 °C, with inrush the same value — the DC coil draws steady current, no AC hum. The diode suppressor means polarity must be observed: reverse connection shorts the diode.
