High Current Circular Feedthroughs - Weldable 700-1750 Volts

High Current Circular Feedthroughs are ideal for applications requiring safe and simple atmosphere side connectivity. These electrical power feedthroughs are rated up to 1750V with use of the supplied High Current Circular Plug. Conductors are insulated with alumina and rated up to 250A. Conductors are silver plated on the atmosphere side to reduce contact resistance. They are designed to be welded into a suitable through-hole in a flange.

Temperature Without Plug: -269°C to 450°C

Temperature With Plug: -55°C to 125°C

Note:

The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties, mechanical design, and the intended operating environment. All electrical ratings are based on operation with one side in dry atmosphere and the other side in vacuum of less than 1 x 10^-4 Torr. All VacuCAD files as well as any dimensions shown or listed in our ordering tables do not include manufacturing tolerances and are provided for reference only.
