The 230 V AC coil includes a built-in bidirectional peak limiting diode suppressor, so you don't need to add an external snubber for inductive load switching. The AC-1 rating of 20 A covers resistive loads like heaters. AC-4 is also listed for plugging and inching duty, though that's harder on the contacts. Heat dissipation is 1.3 W — modest enough that you won't need to derate adjacent components in a dense DIN-rail layout, but worth including in your panel thermal budget if you're stacking several contactors. The 3 NO main poles and 1 NO auxiliary contact are wired via screw terminals. The built-in coil suppression means the control circuit sees less back-EMF, which extends the life of your PLC output or relay driving it.","metaTitle":"Schneider TeSys K LC1K09103P72 Contactor, 3P, 9A AC-3, 230VA","metaDescription":"Schneider Electric TeSys K contactor LC1K09103P72. 3-pole, 9A AC-3 at ≤440V, 4kW motor at 480V. 230VAC coil with built-in suppression.
