It draws 550 VA inrush at 20 °C (cos φ 0.3) and settles to 45 VA holding power, dissipating 12–16 W at 50 Hz. The 338.3 Ω average resistance at 68 °F (20 °C) and 40.94 H closed-circuit inductance define the coil's steady-state draw — useful when sizing the control transformer for a panel with multiple contactors. ## Integration Notes This coil mounts directly onto the TeSys F contactor magnet assembly. The 12–16 W heat dissipation at 50 Hz means the enclosure must allow airflow or derating if multiple coils are ganged in a sealed panel. Ambient operating range is 23–131 °F (-5–55 °C).","metaTitle":"TeSys LX1FF800 Contactor Coil, 800 V AC 50 Hz, Obsolete","metaDescription":"Obsolete TeSys F contactor coil LX1FF800, 800 V AC 50 Hz, 550 VA inrush, 45 VA hold.

A form-fit-function replacement would need to match the 800 V AC 50 Hz coil voltage, the TeSys F mechanical interface, and the 550 VA inrush / 45 VA hold characteristics. Without a published cross-reference, each alternative must be verified against the original contactor's coil cavity and control circuit."},{"question":"How do I source the LX1FF800 given its obsolete status?","answer":"Sourcing runs through surplus and broker channels.
