The LX0FK005 is a TeSys F contactor coil from Schneider Electric, designed as a service part for the TeSys F contactor range. It operates on a 48 V AC/DC control circuit, covering 50 to 400 Hz AC and DC standard, making it a direct drop-in replacement for existing TeSys F contactors that require this coil voltage. The coil's control circuit voltage limits are 0.85 to 1.1 Uc for both latching and unlatching, meaning it holds in reliably at 40.8 V and must not exceed 52.8 V. Average resistance measures 1.57 Ω for the latching winding and 166 Ω for the unlatching winding at 68 °F (20 °C) — these values help confirm the coil is not shorted or open when bench-testing a spare. This suits moderate-duty cycling in motor starter or panel applications where the contactor sees regular but not continuous operation.
The 48 V AC/DC control voltage is the key fit parameter — verify your existing contactor's coil tag matches. The LX0FK005 accepts both AC and DC on the same coil, so it works in panels with mixed control supplies. The 50 to 400 Hz AC range covers 50 Hz and 60 Hz industrial mains without derating. Operating time of 50 to 100 ms for unlatching and 40 to 80 ms for latching means the contactor opens and closes within a predictable window. This matters in sequencing logic where the contactor's dropout time affects interlock timing.
