Vacuum Interrupters Introduces RVI-5259C33 Replacement Vacuum Interrupter

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-5259C33 replacement vacuum interrupter.

This direct fit-and-function replacement unit for the Cutler Hammer/Westinghouse /Square D 5259C33 vacuum interrupter meets original equipment ratings and is intended for use in the 400A AMPGARD Vacuum Break SJ Series SJA50VW430. The RVI-5259C33 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, 7.2 kV RMS maximum voltage, 60 kV peak impulse withstand, and 8.5 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.
