The TeSys LX1FH1402 is a replacement contactor coil for LX1F contactors, rated at 140 V AC control voltage at 40 to 400 Hz. It opens in 100 to 170 ms and closes in 40 to 65 ms — timing that matters when coordinating interlocking or safety circuits in a panel.
Sourcing reality — obsolete, no direct replacement
Schneider Electric has marked the LX1FH1402 as obsolete. If you are holding a legacy LX1F contactor with a failed coil, this is the exact part you need; there is no pin-compatible drop-in from the current TeSys range.
The coil dissipates 8 W at 40 to 400 Hz — a figure to factor into enclosure thermal calculations, especially in a densely packed panel. Maximum operating rate is 2400 cycles per hour at 55 °C, which governs how fast the contactor can be cycled without overheating the coil. Drop-out voltage is 0.35 to 0.55 Uc, operational range 0.85 to 1.1 Uc at 55 °C, so the coil holds in reliably down to about 119 V AC and drops out cleanly below 77 V AC.
