The industry standard in quality

• Each Eaton vacuum interrupter is tested throughout the manufacturing process

and once again before packaging

• A dielectric withstand test and a vacuum assurance test are performed

on every interrupter

• Additionally, Eaton also incorporates a sequential laser-etched bar code that

allows us to track material lots, as well as the operators involved with building

each interrupter in a database

• With well over five million Eaton vacuum interrupters in service around the

world, our customers testify that our vacuum interrupters are one of the most

critical and reliable components 

State-of-the-art testing

Using our two high-power test labs, a single phase development lab in the

United States and a three-phase KEMA®-certified lab in Europe, Eaton

systematically tests new designs before certification by the customer.

A team of scientists and design engineers creates our vacuum interrupters to

meet customer specifications, many of which push the limits of industry standards.

Some distinguishing features include:

• Solid dielectric encapsulation (silicone and heat shrink sleeve offered)

• Customer-specific terminal designs

• Features for ease of assembly

• Custom internal and external threads

• Anti-twist bushings

• Custom contact design: butt contacts, transverse magnetic field (TMF) contacts,

axial magnetic field (AMF)
