The LC1FK43G22 is classified as obsolete (lifecycle stage: eol_hot). This means Schneider Electric has formally ended production; no further manufacturing runs are planned. For a BOM line that requires this exact order code, procurement must source through the independent surplus and broker channel.
The description CONT 3P 2F2O 127V-50HZ tells you this is a three-pole contactor with two normally-open and two normally-closed auxiliary contacts, wound for a 127 V 50 Hz coil. That coil voltage ties it to 127 V control circuits common in certain legacy installations — not the 110 V or 220 V standard in most modern panels, so verify your control transformer tap before specifying. The 2F2O auxiliary block is factory-integrated, saving a separate add-on order.
Deployment context
The TeSys F family uses a screw-clamp terminal system; strip length and torque values follow the standard IEC 60947-4-1 schedule for the frame size.
