Solving the Discontinued Hardware Crisis

Fuji Electric's FMC series contactors were widely deployed across motor control centers and machine control panels throughout the 1980s and 1990s. These components were integrated into systems designed for 20–30 year service lives — systems that are now well past their original design horizon but remain in productive operation because the mechanical and electrical infrastructure around them is sound.

Re-engineering is not a trivial exercise. It requires an automation engineer to map the existing control logic, select a modern contactor with compatible ratings, modify the panel wiring, update documentation, and re-commission the system — all while the line sits idle. For a single contactor, that cost is disproportionate. A verified FMC-3 spare eliminates that entire chain of events.

Condition & Reliability Assurance

• Step 1 – Visual and mechanical inspection: Housing integrity, contact carrier condition, and arc chute examination.
• Step 2 – Electrolytic capacitor assessment: Where applicable, capacitor aging indicators are checked. Bulging, leakage, or elevated ESR readings result in unit rejection.
• Step 3 – Contact surface inspection: Main and auxiliary contact faces are examined for pitting, erosion, and oxidation beyond serviceable limits.
• Step 4 – Terminal and pin corrosion check: All connection points are inspected for corrosion, tin whisker formation, and mechanical integrity.
• Step 5 – Firmware and configuration verification (where applicable): For units with embedded control logic, version consistency with the target application is confirmed prior to dispatch.

Units that do not pass all five stages are not offered for sale. Condition grade (new surplus, tested serviceable, or refurbished) is disclosed at the time of quotation.
