Federal-Pacific TC-546 Load Tap Changer Contacts

The Federal-Pacific TC-546 is a load tap changer found across the utility transformer fleet, and its switching contacts are the primary wear item. The original line is largely out of production, so replacements come from a shop that still makes them. Southern Switch machines and reverse-engineers the full Federal-Pacific TC-546 contact set in-house in Palm Harbor, Florida, to the original dimensional specification, including complete contact kits, reversing switch contacts, arcing contacts, collector rings. Refurbish your worn contacts or order OEM-spec replacements; lead time is confirmed at quote and material certifications are available.

TC-546 contacts and kits.

How we supply them

Refurbished, reverse-engineered, or new.

Send us your worn TC-546 contacts and we refurbish them where the base material is sound. Where it is not, we machine new OEM-spec replacements, and where the OEM part is long gone we reverse-engineer it from a sample, a drawing, or a model number. That is the difference from a catalog seller: we are the shop making the part. Full LTC rebuild service is available when the whole tap changer needs work.

Common questions

Federal-Pacific TC-546 questions.

Are Federal-Pacific TC-546 LTC contacts still available?

Yes. The original Federal-Pacific line is largely out of production, so replacements come from a shop that still makes them. Southern Switch machines and, where the part is obsolete, reverse-engineers the full Federal-Pacific TC-546 contact set in-house in Palm Harbor, FL, to the original dimensional specification.

Can you refurbish my existing TC-546 contacts, or only supply new?

Both. We refurbish customer-supplied Federal-Pacific TC-546 contacts where the base material is sound, and machine new OEM-spec replacements where it is not. Material certifications are available on request.

How fast can you supply TC-546 contacts?

Lead time is confirmed at quote and depends on current material availability. In-stock items ship quickly; reverse-engineered first runs take longer.
