What Vacuum Interrupters does

Vacuum Interrupters, founded in 2010 and headquartered in Denton, Texas, is a specialized manufacturer and service provider focused on replacement vacuum interrupters, vacuum interrupter test equipment, and high-voltage laboratory testing for medium-voltage circuit breakers and contactors. The company's core products include direct fit-and-function replacement vacuum interrupters for discontinued or legacy OEM equipment from Eaton/Cutler Hammer/Westinghouse, General Electric, Rockwell Automation/Allen Bradley, and Federal Pioneer, engineered with Cu-Cr contacts and alumina ceramic construction and compliant with ANSI C37 standards. It also sells proprietary test instrumentation (MAC-TS4 Vacuum Interrupter Test Set, VITS60M Vacuum Integrity Tester, CBT-1203 Circuit Breaker Timer Test Set) and offers encapsulated pole assemblies, vacuum interrupter and SF6 equipment repair services, and high-voltage lab testing and certification.

The company monetizes through quote-based hardware sales of replacement parts and testing equipment, plus professional services revenue from its high-voltage testing laboratory, remanufacturing/repair services, and emergency field support. Its go-to-market is sales-led, supported by a website-based product finder tool that lets customers identify replacement parts by OEM manufacturer and model, a knowledge base of case studies and technical articles, and direct phone-based engagement including a 24/7 emergency support line. Vacuum Interrupters operates as an affiliate within the Group CBS diversified electrical equipment and services network, serving industrial power companies, utilities, and electrical contractors that maintain aging medium- and high-voltage power distribution infrastructure.
