Industrial components manufacturer Eaton Corporation today introduced a new, complete range of W-VACi vacuum medium-voltage circuit breakers 12 kV, 17.5 kV and 24 kV according to the IEC (International Electrotechnical Commission) standard. W-VACi circuit breakers are specially designed to deliver reliability, safety and performance in a compact, environmentally friendly and cost-effective format.
The new W-VACi range complements Eaton's existing family of medium-voltage switching solutions, which builds on the company's long history in vacuum and solid-insulation circuit breaking. W-VACi circuit breakers are guaranteed 100% free of SF6 gas (sulfur hexafluoride).
W-VACi vacuum circuit breakers are designed and certified by an independent body to comply with the latest IEC 62271-100 and IEC 62271-1 standards. To confirm their reliability and longevity, they also meet or exceed the electrical and mechanical endurance requirements E2 and M2, according to IEC 62271-100.
W-VACi circuit breakers are available in 12 kV and 17.5 kV versions according to the IEC standard (up to 50 kA and 3150A or 4000A with forced cooling), and 24 kV (up to 25 kA and 2500A). They can be used in many applications such as the protection of transformers, capacitor banks, motors, busbars or cables, as well as in certain special environments. They can be used in both 50 Hz and 60 Hz in all sectors, including industrial, commercial, services, mining, marine, petrochemical and offshore.
IEC W-VACi circuit breakers consist of three main elements: a vacuum interrupter (VI), epoxy resin encapsulated pole units (EPU) and a universal mechanism assembly (UMA). Each element provides the qualities needed to build a circuit breaker that promotes safety, reliability and performance.
Eaton vacuum interrupters are sealed for life and require no maintenance. For maximum longevity, performance and compactness, the vacuum interrupters are encapsulated in epoxy resin, which protects them against mechanical impacts and environmental stresses such as humidity or dust. W-VACi circuit breakers use a simple modular mechanism, common to all circuit breaker models, which makes the W-VACi family extremely easy to use. Thanks to its modular design, choice of materials and limited number of moving parts, the W-VACi mechanism requires only minimal inspection throughout its service life.
IEC W-VACi circuit breakers offer several safety features for optimum user protection. They are complemented by a full range of circuit breaker accessories that fit all interrupter sizes, allowing users to reduce the number of parts held in stock and simplify their purchasing process. W-VACi accessories are easy to mount and wire, which minimizes installation time and costs.
To give users maximum flexibility, W-VACi circuit breakers are available worldwide in withdrawable or fixed configurations. They can be supplied with Eaton switchgear enclosure kits to integrators or OEM manufacturers, and are also available with Eaton's new IEC Power Xpert® design.
