The LX1LC330 is a replacement coil from the TeSys range, designed for LC1 series contactors. It is the wound component that energizes the contactor's magnetic circuit, pulling the main poles closed when the control voltage is applied. Control circuit voltage is 330 V AC at 50 Hz and 380 V AC at 60 Hz — a dual-frequency rating that covers 50 Hz and 60 Hz mains without a separate tap. Power consumption sits at 12-18 VA sealed (holding) and 170-230 VA inrush at 60 Hz, 0.3 A sealed / 0.55 A inrush. The inrush figure governs the sizing of the control transformer or PLC output driving this coil; the sealed draw is what the thermal budget sees in continuous operation.
Key electrical parameters for fit verification
Average resistance is 392.321 Ohm ±10% at 20 °C. This is the value to compare against a failed coil when troubleshooting an intermittent dropout — a shorted or open winding will deviate well outside the ±10% band. Inductance is 0.107 mH with the magnetic circuit closed (contactor engaged). Open-circuit inductance will differ; this figure is the operating value once the armature seals.
