The LX1FJ175 is a replacement contactor coil for the TeSys F range, designed to energize the contactor's electromagnet when 175 V AC at 50 or 60 Hz is applied to its terminals. It is a field-replaceable component, not a complete contactor — you swap the coil into an existing TeSys F contactor frame when the original coil fails or when you need to change the control voltage.
Sourcing Reality — Obsolete Status
The official replacement is a functionally equivalent TeSys F coil at the same 175 V AC rating; verify the physical mounting matches your contactor frame before committing the order.
The 175 V AC control circuit voltage is specific — it is not a dual-range 110–240 V coil. If your panel supplies 208 V or 240 V control power, this coil will overheat and fail; it is sized strictly for 175 V AC nominal at 50/60 Hz. The coil is part of the TeSys F family, which covers contactors from roughly 115 A to 800 A in AC-3 duty. Confirm the frame size (F115, F150, F185, etc.) matches the coil's mechanical interface — the LX1FJ series fits specific frame variants, not all TeSys F frames.
