Overview
  • The expertise of Powell in vacuum circuit breaker engineering is internationally recognized and our medium voltage designs have been an industry leader for 40 years. We have a commitment to providing the highest levels of operational safety and reliability and used our experience in the ANSI market to design an IEC design and offer the latest in the PowlVac family of circuit breakers.
     
    PowlVac100TM is designed and fully certified to IEC 62271-100 (High Voltage AC Circuit Breakers) and is rated for medium voltage applications through 15kV and 4000A.

  • PowlVac100TM circuit breakers are ideal for medium voltage distribution applications where there is the need for a highly reliable design. This design uses the time-tested Powell circuit breaker mechanism and the experience and expertise of Powell medium voltage circuit breaker technology that has demonstrated customer value for more than three decades. Applications for PowlVac100 would include industrial installations such as oil/gas, refining, petrochemical, power generation and distribution, pharmaceutical, paper and pulp, food and beverage, mining and metals, utilities, transportation facilities where modern IEC design standards are used.

    • Rated up to 15kV and 4000A
    • Power Frequency Withstand up to 36kV 1 min
    • Fully interlocked closed-door operation
    • Circuit breakers and contactors tested in Type 298 cubicle arrangements
    • Peak make currents up to 158kA
    • Asymmetrical switching DC components up to 100%

  • PowlVac100TM circuit breakers and Powell Medium Voiltage Type 298 switchgear/controlgear provide a fully integrated medium voltage electrical distribution solution that rivals any available in the industry today. The design features of the Powell offering include:
     
    • Modular LSC2B construction to IEC 62271-200
