Vacuum Interrupters Introduces RVI-VS-10028 Replacement Vacuum Interrupter

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-VS-10028 replacement vacuum interrupter.This direct fit-and-function replacement unit for the Siemens VS10028 vacuum interrupter meets original equipment ratings and is intended for use in the Siemens GMI, 3AF, FSV, and MSV vacuum circuit breakers, including the 5-3AF-350A-1200-78 and 15-GMI-1000-3000-77. The RVI-VS-10028 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 3000 A RMS-rated current, 15 kV RMS maximum voltage, 95 kV peak impulse withstand, and 37 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.
