Eaton’s Custom Vacuum Interrupters provide 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 minimizes 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 cutoff 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.
