The LX1LB036 is a replacement coil from the Schneider TeSys range, designed to fit TeSys contactors and motor starters that take the LX1 coil platform. It's the part that pulls the contactor in when you apply 36 V AC at 50 Hz. Rated for 36 V AC 50 Hz control voltage, with an inrush draw of 75 VA that drops to 8 VA once sealed. That 75 VA inrush is what you need to budget for in your control transformer sizing — it's a short spike, but it's real.
What the specs mean on the bench
Coil resistance measures 11.01 Ohm at 20 °C, ±10%. That's your go-to check when you're bench-testing a used pull or troubleshooting a no-pickup — a shorted or open coil will read way off that value. Inductance is 0.95 mH, which plays into the inrush current profile. The 8 VA sealed consumption means the coil stays cool in continuous duty — no extra derating for a panel that's packed tight. Mount it on the contactor, wire the A1-A2 terminals, and it's done.
