The TeSys LX1LB340 is a replacement coil for TeSys contactors, not a complete contactor assembly. Coil draws 75 VA inrush at 0.55 power factor, dropping to 8 VA sealed at 0.28 power factor — the sealed hold power is what matters for continuous duty in a panel, keeping heat rise manageable inside the contactor enclosure.
Rated coil resistance is 1060.99 Ohm ±10 % at 68 °F (20 °C). If you are bench-testing a contactor that chatters or fails to pull in, measuring resistance across the coil terminals against this value confirms whether the winding is open or shorted before you swap the part. Inductance is 6.6 H — this governs the magnetizing current and the time constant of the coil circuit. For a 50 Hz supply the inductive reactance is roughly 2 kΩ, which aligns with the sealed VA figure.
