The LX4FL080 is a replacement contactor coil from the Schneider Electric TeSys range, designed for DC low-consumption control circuits at 80 V DC. It's the drop-in energizing component for TeSys contactors that use the FK-style coil platform — you swap the coil, not the whole contactor, when the control voltage changes or the original coil fails.
Coil pull-in and drop-out are governed by the control circuit voltage limits: the coil operates reliably between 0.85 and 1.1 Uc (68 to 88 V DC) at 55 °C, and drops out between 0.2 and 0.35 Uc (16 to 28 V DC). That drop-out window matters for applications where the DC bus sags under load — if your bus holds above 28 V during a brownout, the contactor stays sealed. Opening time is 40 to 50 ms; closing is 60 to 70 ms, which is typical for a DC-operated power contactor and fast enough for most motor and resistive load switching. This coil ships without a built-in suppressor module. That means you need to add an external flyback diode or RC snubber across the coil terminals if the control circuit drives the coil from a PLC output or solid-state relay — the inductive kick from the coil can damage electronics without suppression.
The LX4FL080 is listed as an active product. It is a service part — not a full contactor assembly — so it is typically quoted to order rather than sitting on a shelf.
