Vacuum circuit breakers: New-Auto. V series

Digital multifunctional relay has versatile features.

The New-Auto.V is a circuit breaker that consists of a standard MULTI.VCB provided with a CT (current transformer), and incorporates a multiple function protectors and controllers to prevent equipment from overcurrent and other factors, thus saving energy and reducing installation man-hour.
• Multiple function protectors and controllers offers versatile features such as ground-fault directional, ground-fault overvoltage, undervoltage, and overvoltage protective functions in addition to overcurrent protection. It also includes measurement functions for a variety of items, such as current, voltage, power, power-factor, frequency, and zero-phase voltage values.

Multiple function protectors and controllers offersversatile features

Draw-out type MW or PW (Y type)
  • A host of protective functions
    • Provided with ground-fault directional, ground-fault overvoltage, undervoltage, and overvoltage protective functions in addition to overcurrent protection.
    • Allows precise settings for relay operation characteristics, to ensure easy protective coordination.
  • Additional measurement functions
    • Includes measurement functions for a variety of items, such as current, voltage, power, power-factor, frequency, and zero-phase voltage values.
  • Equipped with transducer and communications functions.
    • The transducer function (4 channels) enables the use of analog meters.
    • The communications function (RS-485) enables status and other monitoring items.

Wide-range CT supports equipment across a wide capacity range

Multiple function protectors and controllers
  • Range of operating current settings for overcurrent protection: 15 to 390A
  • Covers an equipment capacity range of 170 to 4,400kVA.
  • Instantaneous operating current: 1x to 20x CT rated current (at 0.2x increments)
  • Time-lag time-magnification: Setting between 0.5 and 100

Greatly simplifies main circuit connections

Toroidal wide-range CT
  • The compact, built-in CT eliminates the need for CT space or CT installation work on distribution boards.
