About the Federal Pacific TC 546 Load Tap Changer
The Federal Pacific TC 546 is a load tap changer with a diverter switch roller contact assembly, inner collector ring, wedge contacts, and reversing switch contacts. The diverter switch roller contact assembly is the primary wear component, with the wedge contact and collector ring also requiring attention at maintenance intervals. Southern Switch machines TC 546 replacement 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.
