    03/31/2025

    ­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-RP177B replacement vacuum interrupter.

    This direct fit-and-function replacement unit for Allen-Bradley RP177B vacuum interrupters meets original equipment ratings and is intended for use in Allen-Bradley 1502-V4DBDA-1 contactors. The RVI-RP177B 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 6 kA RMS-rated short-circuit breaking current.

    No modification is required for proper installation and operation in the existing Allen-Bradley 1502-V4DBDA-1 contactors. Vacuum Interrupters can also provide assembly components and mounting hardware to aid in installation and shorten downtime.
