The LX1FF800 is a replacement coil for TeSys F contactors, wound for 800 V AC 50 Hz control circuits. 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).
