GE built more North American LTCs than any other manufacturer. Many of them are still running 40 to 60 years after install. Southern Switch & Contacts supplies replacement contacts and complete refurbishment kits for the GE LTC families that show up most often in service.
The GE LR series (LR65 and LRT65) is a resistance-type design that dominated distribution substations through the 1960s and 70s. The LRT200 is the higher-amperage variant for transmission service. The ML-32 and MLT-32 are different mechanical families that show up on older McGraw-Edison and GE distribution transformers.
Every kit page below lists the constituent parts with internal SKUs and quote-only pricing. Material certifications are available on request. Reverse-engineered parts are stocked or machined to order for the items GE no longer supplies.
The GE LR and LRT diverter-switch design uses spring-loaded arcing fingers that take the brunt of every tap change. After 50,000 to 100,000 operations the fingers lose tension and the arcing surfaces pit enough to raise contact resistance. Replacing the arcing fingers and re-facing the main contacts brings the LTC back to its original interrupting characteristic.
