Part Profile
The LC7K09017FE7 is a Schneider Electric TeSys K 3-pole contactor with a 115 V AC coil and one normally closed auxiliary contact. It's rated for AC-3 duty at 9 A up to 440 V, and carries motor power ratings of 4 kW at 480 V, 500–600 V, 660–690 V, 380–415 V, and 440 V AC, plus 2.2 kW at 220–230 V AC, all at 50/60 Hz. The AC-1 and AC-4 utilisation categories are also covered, meaning it handles resistive loads and inching/jogging duty as well.
For resistive (AC-1) or plugging/inching (AC-4) duty, the rated operational current is 20 A, so the same contactor handles higher resistive loads but the AC-3 figure governs typical induction motor applications. The 4 kW across multiple voltage bands (480 V through 690 V) confirms it's sized for standard three-phase motors in that power class globally, not just one regional voltage. Heat dissipation is 3 W — low enough that multiple units can be ganged on a DIN rail without forced cooling in a standard IP20 panel. The 3-pole configuration (3 NO main poles) with a single NC auxiliary covers basic control interlocking; if you need more aux contacts, plan an add-on block.
This is a panel-mount contactor for motor control in industrial machinery, conveyors, pumps, and compressors. The 45 mm width and 58 mm height fit standard TeSys K rail or screw-mounting footprints — common in small-to-medium control panels where space is tight. The 115 V AC coil is a North American standard control voltage; verify your control transformer or PLC output matches.
