Proven vacuum interrupter technology

Environmentally focused circuit protection for global innovation

Vacuum interrupter technology

Eaton’s vacuum interrupter technology is used for repetitive switching, motor inrush

current interruption, fault protection, and overcurrent and short-circuit protection.

Eaton‘s environmentally friendly medium-voltage interrupters are capable of reliably

switching high-stress currents robustly and carrying their rated continuous current

without forced cooling.

• Controlled contact erosion results in long life and maintenance-free operation

• Hard contact material minimizes contact sticking in a vacuum and is ideal for

high-current applications

• Atmospheric contact contamination is eliminated because oxides and corrosion

layers cannot form on the contacts

• Noise and flash free: All arcing is confined in the vacuum interrupter

• Environmentally friendly: Unlike other solutions that use SF6 (a highly hazardous

gas) for insulation, Eaton’s vacuum interrupters feature current interruption

that occurs in a vacuum and does not emit greenhouse or toxic gases

• Low average chopping current results in a minimal induced transient voltage

spike; therefore, suppressors are often not required

• Vacuum dielectric permits contacts to be arranged closer together, allowing

circuit interruptions to be designed in a smaller envelope

• Solid insulation increases external dielectric performance
