Vacuum Interrupters

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-35250 replacement vacuum interrupter.

This direct fit-and-function replacement unit for the Square D WL-35250 vacuum interrupter meets original equipment ratings and is intended for use in the Square D VisiVac vacuum circuit breaker. The RVI-WL-35250 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 600 A RMS-rated current, 15 kV RMS maximum voltage, 95 kV peak impulse withstand, and 12.5 KA RMS-rated short-circuit breaking current.

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