The Schneider Electric LX9FJ923 is a specific contactor coil for the TeSys F range, designed to be the replaceable electromagnetic actuator for the corresponding contactor frame. It is not a standalone contactor — it is the coil assembly that, when energized, pulls the contactor's armature to close the main poles. The control circuit accepts both 84 V DC and 89...99 V AC at 40...400 Hz, making it flexible for panels with mixed control voltages. Opening time is 60 ms, closing time is 20 ms, which governs how quickly the contactor responds to a control signal — relevant for sequencing logic or safety circuits where timing matters. Heat dissipation runs 11.4...13.9 W, which must be accounted for in panel thermal calculations, especially when multiple contactors are ganged in an enclosure. The coil has no built-in suppressor module, so an external RC snubber or varistor is needed across the coil terminals if driving from a PLC output or solid-state relay. Inrush power is 500 VA at 68 °F (20 °C), with hold-in consumption dropping to 23 VA — a typical AC coil profile that the control transformer must be sized to handle during the pull-in transient.
Integration Notes for Panel Builders
Mounts directly onto the TeSys F contactor frame — no adapter or bracket needed. The coil terminals are screw-type, accepting solid or stranded wire up to the contactor's terminal capacity. Ambient operating temperature range is 23...131 °F (-5...55 °C), so it is fine for most indoor panel environments but not for direct outdoor exposure without a heated enclosure. Control circuit voltage limits: operational range is 0.85...1.1 Uc at 131 °F (55 °C). Drop-out occurs at 0.3...0.5 Uc.
