The Schneider LX9FL927 is a specific contactor coil from the TeSys F range, designed to replace or service the coil assembly on TeSys F contactors. It is a low-consumption DC coil rated for a control circuit voltage of 135...149 V DC, with an operational voltage range of 0.85...1.1 Uc at 131 °F (55 °C) and a drop-out threshold of 0.3...0.5 Uc. The coil draws an inrush power of 733 W at 68 °F (20 °C) and settles to a hold-in power consumption of 48 W at the same temperature. Heat dissipation runs between 22.8 and 27.8 W during continuous operation. Switching performance is defined by a 60 ms opening time and a 20 ms closing time, with a maximum operating rate of 1800 cycles per hour at 158 °F (70 °C). Mechanical durability is rated at 5 million cycles.
The coil carries no built-in suppressor module, so any external flyback diode or RC snubber must be added by the panel builder to protect the control circuit from inductive kickback on de-energization.
The coil accepts AC control at 40...400 Hz or low-consumption DC, but the specified voltage range is 135...149 V DC only. Verify your control transformer or DC supply delivers within that band at the coil terminals under load, accounting for voltage drop across wiring and any series suppression components. Ambient temperature for operation is rated from -5 to 55 °C (23...131 °F). The hold-in power of 48 W means the coil runs warm; ensure adequate ventilation inside the enclosure if multiple TeSys F contactors are ganged together.
