Vacuum Circuit Breaker Services, Repair and Replacements
Bay Power supports vacuum circuit breakers through in-house testing, repair, and upgrade services designed to extend the life of your existing equipment. Our PEARL-certified technicians handle inspection, testing, maintenance, repair, and upgrades to keep your electrical systems operating safely and reliably. For many customers, servicing existing breakers is the fastest and most cost-effective way to avoid downtime. We can also help with preventative maintenance schedules to help prevent future failure risk.
When replacement is required, we also supply vacuum circuit breakers from ABB and other leading manufacturers - we are an authorized ABB distributor. We support common medium voltage classes including 5kV, 15kV, and 38kV. From direct replacements to retrofit solutions and hard-to-find models, we help you identify the right option and deliver it quickly.
