About the Westinghouse UTT/UTTA
The Westinghouse UTT and UTTA are transfer-switch type load tap changers found in a large number of utility distribution and power transformers built from the 1960s through the 1980s. The transfer switch makes and breaks load current through the sliding finger contact assembly while the selector and reversing switches position the next tap. The sliding finger contact assembly, collector ring, and transfer switch stationary contacts are the high-wear components. The silver contact surface erodes with each switching operation, and contact resistance rises when the plating wears through to the copper base. The UTTA is a variant of the UTT with minor design differences; both are fully supported with contacts, kits, and hardware.
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.
Stock, lead time & reverse engineering
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.
