Known for its unmatched inventory of new, legacy, and hard-to-find equipment, CBS combines decades of technical expertise with a forward-looking approach to service, safety, and sustainability.
Circuit Breaker Sales (CBS) is a proud member of Group CBS, a global leader in electrical equipment manufacturing, supply, and service. With 31 locations worldwide and more than 600 employees, Group CBS companies share one unified purpose: to deliver complete electric power system life cycle solutions built to the same high standards as the U.S. power grid. It’s what Group CBS calls the Power of One, and this commitment to reliability and innovation has made CBS a trusted partner for utilities, manufacturers, data centers, and other organizations that depend on safe, continuous power.
Known for its unmatched inventory of new, legacy, and hard-to-find equipment, CBS combines decades of technical expertise with a forward-looking approach to service, safety, and sustainability. Whether customers need a replacement breaker, complex retrofill services, or a fully integrated maintenance plan, CBS delivers with the power of one group focused on one goal.
A Trusted Partner for the Industry’s Challenges
The global appetite for electrical power shows no signs of slowing, placing new demands on utilities and industrial operators alike. As organizations expand operations and modernize infrastructure, they face a twofold challenge: how to integrate new equipment effectively while also maintaining and extending the life of existing assets.
Mission-critical systems — from hospitals and airports to manufacturing plants and data centers — cannot be allowed to run to failure. A single interruption can mean costly downtime, safety hazards, and compliance violations. That is why CBS encourages customers to embrace scheduled electrical maintenance programs supported by its expert repair teams and extensive parts inventory. By investing in preventive maintenance, operators not only maximize equipment life but also safeguard uptime and ensure compliance with evolving safety standards.
In this regard, CBS serves as a trusted compliance partner. The company helps customers navigate the complexities of standards from the National Fire Protection Association (NFPA), such as NFPA 70B (Recommended Practice for Electrical Equipment Maintenance) and NFPA 70E (Standard for Electrical Safety in the Workplace). By aligning with these standards, customers reduce risk, protect workers, and ultimately lower long-term costs compared to the financial and operational impact of downtime or violations.
Investments and Acquisitions Expand Coverage and Expertise
CBS has steadily expanded its reach and capabilities since 2018, when it opened a new flagship facility and joined with Group CBS companies under a growth-focused strategy. Several strategic acquisitions have expanded both geographic coverage and service expertise.
Exstar, acquired in 2019, strengthened CBS Northeast’s footprint in the Boston area, enhancing maintenance, testing, and equipment service capabilities. National Circuit Breaker, Switchgear Power Solutions, and Premier Power Maintenance were all brought into the Group CBS fold in 2024. The acquisition of National Circuit Breaker, now Circuit Breaker Sales Los Angeles, extended CBS’s presence on the West Coast, providing rebuilds, life-extension services, and field support for everything from high-rises in Los Angeles to critical utilities in the Bay Area. Switchgear Power Solutions added depth in the Midwest, broadening CBS’s inventory of both current and legacy equipment — ranging from small circuit breakers to large power transformers.
Field services are another critical piece of the comprehensive life cycle model. With the acquisition of Premier Power Maintenance, Group CBS added to the network of NETA-certified technicians offered by CBS Field Services, enabling nationwide support for installation, acceptance testing, preventive maintenance, and emergency response. Backed by a 24/7 service commitment, the group is positioned to respond rapidly to customer needs anywhere in the country.
Accolades for an Electrical Safety Innovator
Group CBS companies are known for developing innovative solutions that meet emerging industry needs. CBS ArcSafe, for example, is a global leader in remote racking and switching equipment. Its custom-designed safety solutions have won more than 20 industry awards for innovation in electrical safety.
Vacuum Interrupters, another Group CBS company, is the sole provider of vacuum interrupters manufactured in the United States and an innovator in diagnostic test equipment for circuit breakers and vacuum interrupters. Its proprietary magnetron atmospheric condition (MAC) testing provides unparalleled insights into the condition of components critical to reliable power distribution. Group CBS also operates one of the few independently owned high-voltage test laboratories in the United States, underscoring its commitment to quality and safety.
These innovations have been recognized not only through product awards but also through individual accolades for Group CBS employees from organizations such as NETA and the Department of Defense’s Employer Support of the Guard and Reserve (ESGR).
Commitment to Sustainability
Sustainability is central to CBS’s mission. The company’s maintenance, repair, and remanufacturing services extend equipment life, reducing the need for new equipment and minimizing the waste stream associated with discarded electrical apparatus. This life-extension approach yields clear environmental and economic benefits, including less reliance on backup diesel generators, which means lower emissions, less air pollution, and reduced fuel consumption. Retrofit and retrofill services reuse materials and prevent legacy equipment from ending up in landfills.
CBS Nuclear Services further demonstrates this commitment by specializing in Class 1E safety-related switchgear and circuit breakers, with full compliance to 10 CFR 50 Appendix B requirements.
In addition, several Group CBS companies, including Circuit Breaker Sales, have earned ISO 9001 and ISO 14001 certifications for quality management and environmental stewardship. CBS and Advanced Electrical & Motor Controls (AEAMC) are also active members of the Professional Electrical Apparatus Reconditioning League (PEARL), advancing industry-wide efforts in responsible recycling and reuse.
Looking Ahead: A Strategy for Growth
Group CBS is pursuing a strategic growth plan to build the most comprehensive electrical equipment supply and service network across North America and around the world. With offices in the United Kingdom and South Korea and growing interests in the Middle East, the company is positioned as a truly global partner in electrical power solutions.
The guiding vision is simple but powerful: deliver complete electric power system life cycle solutions. By combining deep technical expertise, the industry’s largest inventory, award-winning innovations, and a nationwide network of service providers, Circuit Breaker Sales is helping customers meet today’s challenges — and prepare for tomorrow’s.
At every stage of the power equipment life cycle, CBS delivers on the promise of the Power of One: one group, one goal, one trusted partner for electrical system reliability.
