About the Federal Pacific TC 525 Load Tap Changer
The Federal Pacific TC 525 is a load tap changer produced by Federal Pacific Electric and found in Federal Pacific transformer nameplate units across utility fleets. Its arcing contact and reversing stationary contact are the primary replacement items at overhaul. Southern Switch machines TC 525 arcing contacts and reversing stationary contacts to OEM dimensional specifications.
Why replace worn LTC contacts
Worn or burned tap-changer contacts raise resistance, run hot, and can lead to tap-changer failure. Precision replacements restore reliable switching and extend the service life of the LTC.

Lead time is confirmed at quote; discontinued or hard-to-find parts are reverse-engineered from a sample, a drawing, or a model number. Based in Palm Harbor, FL, Southern Switch & Contacts manufactures and ships replacement parts to utilities nationwide, and has served the industry since 1982.
