Vacuum Interrupters Introduces RVI-PV-74A 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-PV-74A replacement vacuum interrupter.

This direct fit-and-function replacement unit for General Electric PV-74A vacuum interrupters meets original equipment ratings and is intended for use in GE Limitamp CR193D, CR193VB, and CR193WB contactors. The RVI-PV-74A is built to provide excellent high-voltage insulation, high cumulative and breaking capacity, exclusive internal torsion control, and an excellent vacuum seal thanks to its 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 7 kA RMS-rated short-circuit breaking current.

No modification is required for proper installation and operation in the existing GE Limitamp CR193D, CR193VB, and CR193WB vacuum contactors. Vacuum Interrupters can also provide assembly components and mounting hardware to aid in installation and shorten downtime.
