We provide replacement design and retrofit solutions for aging ABB medium-voltage circuit breakers. Our VTZ series directly replaces ABB VD4-12, VD4-17.5, VD4-36, and VD4-40.5 models - same dimensions, same mounting interfaces, drop-in fit. This gives users a cost-effective alternative to OEM replacements, with shorter lead times, full standard compliance (GB/T1984-2014, GB/T11022-2011, IEC 62271-100), and a 20-year service life. Ideal for power plant upgrades, metallurgical facility renovations, and any 10-40.5kV breaker replacement project.
