Vacuum Interrupters Introduces RVI-WL-35774D 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-WL-35774D replacement vacuum interrupter.

This direct fit-and-function replacement unit for the WL-35774D vacuum interrupter meets original equipment ratings and is intended for use in Eaton SL and Cutler-Hammer SJ25V830 vacuum contactors. The RVI-WL-35774D is built to provide excellent high-voltage insulation, high cumulative and breaking capacity, exclusive internal torsion control, and an exceptional vacuum seal thanks to a fine alumina ceramic.

The replacement vacuum interrupter offers 800 A RMS-rated current, 7.2 kV RMS maximum voltage, 65 kV peak impulse withstand, and 12.5 kA RMS-rated short-circuit breaking current.

No modification is required for proper installation and operation in existing Eaton SL and Cutler-Hammer SJ25V830 vacuum contactors. Vacuum Interrupters can also provide assembly components and mounting hardware to aid in installation and shorten downtime.
