Overview
The LX9FL935 is a Schneider TeSys F specific contactor coil, order code LX9FL935, rated for 400 V AC at 40-400 Hz low consumption, drawing 830 W and consuming 47 W in steady state. It is designed for use with TeSys F LC1F contactors, specifically the LC1F630 frame, and mates with the DR5TE rectifier. The coil carries no built-in suppressor module and is packaged as a single PCE unit.
Function & operation
This coil energizes the LC1F contactor armature when 400 V AC is applied across its terminals, drawing 830 W during inrush and settling to 47 W holding power. The AC 40-400 Hz low-consumption design keeps thermal rise in check across a wide frequency range. The coil operates with a 60 ms response time and is rated for 1800 cycles per hour at 70 °C ambient. Mechanical life is 5 Mcycles. Heat dissipation runs 22.8 to 27.8 W, so panel ventilation should account for that continuous load. Compatibility extends to the DR5TE rectifier and LC1F630 contactor; the coil is a drop-in replacement for those specific frames. No built-in suppressor means an external RC snubber or varistor may be needed for inductive load switching.
Applications
TeSys F contactor coils like the LX9FL935 are used in motor control centers, switchgear, and heavy industrial automation where large contactors switch motors, transformers, and resistive loads. The 400 V AC coil suits 380-400 V line supplies common in European and Asian installations.
