The LX1LC1259 is a replacement coil from the Schneider Electric TeSys range, designed for TeSys contactors and starters that take a separable LX1-series coil. It is the control-side component that pulls the contactor in — not the power poles. The control circuit voltage is 125 V AC at 50/60 Hz, so it is a drop-in swap for any TeSys contactor originally fitted with a 125 V AC LX1 coil.
Coil resistance measures 96.939 Ohm ±10 %, which is the value a field-service tech would check with a multimeter to confirm the coil is not shorted or open before installing. The inductance is 0.107 mH in the closed-circuit (sealed) position — that is the holding state after the contactor pulls in. Power consumption is specified in VA rather than watts because the coil is an inductive load. Inrush draw is 170...230 VA at 0.55 power factor, 60 Hz — this is the surge the control transformer sees when the contactor first energizes. Sealed (holding) draw drops to 12...18 VA at 0.3 power factor, 60 Hz. That inrush-to-sealed ratio of roughly 10:1 is typical for AC-operated contactor coils and matters for sizing the control transformer: the transformer must support the inrush without voltage sag that could prevent the contactor from pulling in cleanly.
