VSA three-phase recloser

Eaton's Cooper Power series VSA group electronically controlled, three-phase, automatic circuit reclosers with vacuum interrupters, provide reliable and economic overcurrent protection to meet a variety of line and substation applications for 15 kV systems (up to 1200 A continuous/ 20,000 A interrupting current). Recloser operations are programmed on the electronic control panel with accurate, preset tripping characteristics and reclosing times, enabling close coordination with other protective devices on the system. When system requirements change, program settings are easily altered with no sacrifice of accuracy or consistency. Recloser and control accessories enable further tailoring of the protective program to achieve maximum system operating flexibility.

Core features

  • Available with ratings up to 1200 amps continuous and 20,000 amps interrupting current, for line and substation applications
  • A choice of electronic recloser controls enables the user to meet a wide variety of application requirements
  • Vacuum as the interrupting medium and air as the insulating medium improves safety and substantially reduces long term maintenance costs
  • The variety of available VSA ratings permits the user to select precisely the right recloser for the protection required
  • VSA reclosers are furnished in standard frames with corner lifting eyes; mounting equipment is available for either pole or substation installation of the recloser 

Vacuum interruption reduces maintenance costs

Vacuum interrupters provide fast, low energy arc interruption with long contact and interrupter life and low mechanical stress. With arc interruption taking place in a vacuum, contact and interrupter life are four times greater than with interruption in oil. At the same time, mechanical stress and wear on the mechanism is substantially reduced. Combined, these factors result in greatly reduced maintenance costs over the life of the recloser.

Form 6 recloser control for maximum flexibility

Eaton's Cooper Power series Form 6 recloser control provides maximum protective hardware design and simple interactive graphical interfaces for complete user customization. ProView software is used to configure control settings, record metering information and establish communication parameters. It also provides analysis tools that include fault locating, event recording and oscillography functions. In addition, the Form 6 rack mount substation interface accessory enables application of Form 6 rack mount controls and VSA reclosers to substation installations. Located in the motor operator cabinet, the substation interface accessory allows the Form 6 rack mount control to be located up to 500 ft. from a VSA recloser.
