Customised vacuum interrupters

Vacuum interrupters

Eaton’s customised vacuum interrupters offer long life and low maintenance, save space and reduce costs. They’re often used for repetitive switching, motor inrush current interruption, fault protection and overcurrent and short circuit protection. Users will appreciate the noise-free and flash-free vacuum interrupter, with rated line-to-line voltages and short-circuit current ratings. Solid insulation increases external dielectric performance. This environmentally-friendly product meets IEEE/ANSI, IEC and GB/DL standards.

Core features

Controlled contact erosion results in long electrical life and maintenance-free operation.
Hard contact material minimises contact sticking in a vacuum and is ideal for high current applications.
Atmospheric contact contamination is eliminated since oxides and corrosion layers cannot form on the contacts.
Noise-free and flash-free as all arcing is confined inside the vacuum interrupter.
Environmentally-friendly product since current interruption occurs in a vacuum and does not emit greenhouse or toxic gases.
Low average cut-off current results in a minimal induced transient voltage spike so surge suppressors are not required.
Vacuum dielectric allows contacts to be arranged closer together so circuit interruptions can be designed in a smaller envelope.
Solid insulation increases external dielectric performance.

A heritage of innovation

Since first setting out to develop an efficient, economic vacuum interrupter over 100 years ago, Eaton has been at the forefront of innovative, safe technology.

The perfect fit

Eaton's customised vacuum interrupters are a perfect fit for various markets and applications including utilities, oil and gas, petrochemical, data centres, mining, OEM, military, institutional, commercial and wind power.

Interrupting power safely

At Eaton, safety is a high priority. That’s why we put valuable time and effort into industry-leading circuit protection, ultimately helping to keep you and your customers safe. Purchasing counterfeit or reused vacuum interrupters from an unauthorised source can put your reputation and your worker’s safety at risk.
