Obsolete — what that means for your BOM
The LX1LB024 is marked obsolete by Schneider Electric. No official successor is listed on the manufacturer's records. This coil was part of the Integral 18 contactor range, designed for 24 V AC 50 Hz control circuits. The 5.17 Ohm coil resistance at 20 °C and 0.23 mH inductance define the control circuit load — a PLC output or relay driving this coil must handle the 75 VA inrush (0.55 power factor) and 8 VA sealed hold.
Sourcing an obsolete Integral 18 coil
Since Schneider no longer manufactures the LX1LB024, supply runs through independent surplus and decommissioned-line recovery channels. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here. A buyer sourcing this for a line-down situation should verify the coil's DC resistance matches the 5.17 Ohm ±10 % spec before committing — a pulled coil that reads open or shorted is scrap. The 24 V AC 50 Hz control voltage is non-negotiable; a 24 V DC coil will not hold in on AC and vice versa.
What the coil ratings tell a maintenance planner
The 75 VA inrush at 0.55 power factor means the control transformer or power supply feeding this coil must be sized for the magnetizing surge, not just the 8 VA sealed draw. A 100 VA transformer is the practical minimum for a single coil; multiple coils on the same circuit need the inrush summed. The 0.23 mH inductance is the coil's open-circuit value — once the armature seats, the inductance rises and current drops to the sealed level. If the contactor chatters or fails to seal, the inductance measurement at the coil terminals (with the armature held open) confirms whether the coil is intact.
