Vacuum Interrupters, a manufacturer of replacement vacuum interrupters, pole assemblies, parts and components for medium-voltage circuit breakers and contactors, introduced the RVI-WL-35774D replacement vacuum interrupter. This replacement unit for the WL-35774D vacuum interrupters is a direct fit-and-function unit, meeting original equipment ratings. It 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 company says. This replacement vacuum interrupter offers 800 A RMS-rated current, 7.2 kV RMS maximum voltage, 65 kV peak impulse withstand, as well as 12.5 kA RMS-rated short-circuit breaking current. Vacuum Interrupters notes that no modification is required for proper installation and operation in existing Eaton SL and Cutler-Hammer SJ25V830 vacuum contactors. The company also can provide assembly components and mounting hardware to aid in installation and shorten downtime.
