- Description
- Technical Specifications
-
The design and manufacturing of the VD4 vacuum circuit breaker follow relevant standards such as GB and DL, adopting ABB's renowned vacuum interrupter and advanced insulating material poles, as well as a reliable operating mechanism. It is a perfect combination of ABB Group's global R&D design and manufacturing technology, with rich global operational experience, widely used in public facilities, industry, transportation, construction, and other distribution fields.
The VD4 vacuum circuit breaker uses solid-sealed pole technology to ensure the vacuum interrupter is reliably protected, avoiding the effects of mechanical impact, dust, and moisture. Innovative modular functional design, compact size, spring energy storage operating mechanism, standard anti-trip function, stable performance, and long service life. Fixed or withdrawable installation, complete secondary accessories and safety interlock solutions available. Additionally, the manufacturing, operation, and recycling processes are energy-saving and low-carbon, environmentally friendly.
