The LX1FX380 model from Schneider Electric's TeSys line is designed as a magnetic coil compatible with the LC1F series of contactors, specifically the LC1F780. It functions effectively within a control-circuit frequency band that spans from 40 Hz to 400 Hz. The nominal control voltage for this coil is specified between 380 and 400 volts AC, ensuring stable operation under various conditions.

Regarding its electrical characteristics, the coil has a closed-circuit inductance value of 2.3 H. Its resistance measures 60.9 Ω during inrush conditions and 2780 Ω while in a holding state at 20 °C. For operational responsiveness, the device features an energizing response time of 40 to 80 milliseconds when activating and a de-energizing response time ranging from 130 to 230 milliseconds when disengaging.

In terms of durability, the LX1FX380 exhibits impressive mechanical endurance, rated for up to 5 million cycles, which enables it to sustain heavy-duty applications. It is also capable of achieving a maximum switching throughput of up to 600 cycles per hour at a temperature of 55 °C.

Power consumption is recorded as 2,100 VA upon inrush with a power factor (cos φ) of 0.9, and it draws 50 VA in holding state with a lower power factor of 0.3. Its thermal dissipation reaches 44 watts, indicating the heat generated during operation, which must be managed effectively for reliable performance.
