Customized design
 
  • Minimized dimension difference of ACBs make easy to design switchboards. Breakers can also be replaced according to system specification changes.
  • All type ACBs have same panel cut-out size, so it is also easy to standardize the switchboard design.
  • All circuits and manual operation parts are in front side. This front mounted design enables easy wiring, operation and inspection.
  • Easy insertion to cradle, line and load side reverse connection and convienient replacement of APR, trip device and motor also offer greater satisfaction to customers.

Safety provision

  • The fully molded body increases the safety in any application.
  • The neutral pole contact closes earlier than the main cirucit contacts and opens later.
  • This early-make late-break N pole contact effectively prevents the occurrence of the abnormal voltages between the phase lines and the neutral line, thus ensuring safety.
  • Internal surge protection device suppresses the surge of ACB itself and protects against mis-operation of loads.
  • Various accessories also contribute to safety features.

Various accessories and options

  • Varrious accessories are available for better safety, convenience and performance of ACBs.
  • All accessories are easy to install and maintain.
  • Extensional auxiliary switch (1a1b)
  • Key lock device (lock in open)
  • Cycle counter
  • Door flange
  • Lifting lugs
  • Button lock cover
  • Neutral CT
  • Mechanical interlock device
  • Spring charge switch

  • Vertical type bus-bar
  • Short circuit 'b' contact
  • Position switch
  • Wrong inserting pervention device
  • Arc shield
  • 100% size neutral pole
  • Test jumper
  • APR checker
 

Introduction of HiAH & HiAS type

Both HiAH & HiAS type ACB are based on the HiAN type. By adopting different technology, they can cover all applications together with HiAN type.

  • HiAH type
    HiAH type ACB has the highest breaking capacity in the world, especially for marine use or in power plants. Wide current from 630A to 3200A can be realized in the same frame.
  • HiAS type
    HiAS type ACB is best suited for simple application with lower breaking capacity and compact size compared to HiAN type.
