The LX1LC660 is a replacement coil from the Schneider TeSys range, designed for LC1 contactors that need a 660 V AC 50 Hz control circuit. It's the part you pull when the original coil burns out or the line voltage is 660 VAC — not a common voltage, but when you need it, nothing else drops in.
Coil resistance measures 1602.9 Ohm ±10% — that's the DC resistance you'll read across the terminals with a multimeter. The closed-circuit inductance is 0.107 mH, which governs the inrush current profile. Power consumption: 12...18 VA sealed at 60 Hz, but inrush hits 170...230 VA at 0.55 power factor. That inrush spike matters for the control transformer sizing — a 100 VA transformer won't hold it if multiple coils pull simultaneously.
