Farmers Branch, TX, June 19, 2023 — Vacuum Interrupters, a leading manufacturer of replacement vacuum interrupters, pole assemblies, parts, and components for medium-voltage vacuum circuit breakers and contactors, introduces the RVI-6716C40 replacement vacuum interrupter. 

At just 3.1 inches in length, it is the smallest interrupter in our lineup. This direct fit-and-function replacement unit for the Eaton, Cutler Hammer, or Westinghouse 6716C40 vacuum interrupter meets original equipment ratings and is intended for use in the Eaton V200 and V201K CJZ1 vacuum motor controller/contactor. The RVI-6716C40 is built to provide excellent high-voltage insulation, high cumulative and breaking capacity, exclusive internal torsion control, and an excellent vacuum seal thanks to a fine alumina ceramic.  

The replacement vacuum interrupter offers 400 A RMS-rated current, 1.14 kV RMS maximum voltage, 10 kV peak impulse withstand, and 3.2 kA RMS-rated short-circuit breaking current.  

No modification is required for proper installation and operation in the existing electrical equipment. Vacuum Interrupters can also provide assembly components and mounting hardware to aid in installation and shorten downtime.
