1. VITZROTECH ACB(AIR CIRCUIT BREAKER) INTRODUCE 

  

 ● VITZRO TECH Air Circuit Breaker is designed and manufactured to maintain various systems and 

     compatibility that more than meets the requirements of customers. It provides a convenience by  

     reducing the working hours when newly installing or expanding the device. In addition, it is equipped  

     with an intelligent protective function and a high-precision option protective function that provides the  

     best convenience for users since it can be used quickly and easily.

 

 ● VITZRO TECH Air Circuit Breaker is a circuit breaker that passed new IEC standard (IEC60947-2,  

     LV switch equipment and control equipment circuit breaker) and KS standard (KSC 4620)

     development  tests. It is a premium circuit breaker that is convenient to use with a design that enables  

     a short breaking time and maximum safety and protection functions.

 

 ● Performance _ It provides a stable image and an excellent breaking performance. 

    - The front part and mechanism part of the product are molded using an insulator to increase the safety 

       of operators. 

    - The reliability of the product is enhanced based on a precise configuration and an excellent breaking 

       capacity. 

    - It is easy to perform maintenance using an overheat alarm function that detects the temperature of  

      Busbar (R, S, T, N). 

    - It has a superior switch performance and an excellent durability. 

 

 ● Easy _ It is easy to perform maintenance and the parts are compatible. 

    - The mechanism part and auxiliary device are modularized for easy maintenance. 

    - An overheat burn prevention function is built-in through a Shunt Coil. 

    - The parts are closely connected which enables a convenient maintenance of users.  

 

 ● Compact _ It ensures a sufficient space for customers using a compact and lightweight device. 

    - It is a compact product that is optimized for package panel system. 

    - An external size is reduced to 80% of the existing product which allows loading of 3 LV boards. 

 

 ● Intelligent _ It is designed in a safe and convenient configuration by applying an Intelligent Trip  

                           Device. 

    - It is easy to distinguish a trip state using a LED of the Intelligent Trip Device. 

    - It satisfies the requirements of an intelligent control center and automation system such as a remote 

      measurement, a remote control and so forth since it has a standard RS485 communication interface 

      of  the Intelligent Trip Device.

    - It is easy to monitor in precision (indicating, protecting, setting, breaking) from a low current (1A) to 

       a maximum current (4000A). 

 

 ● Convenience _ It enhanced the users’ convenience and safety. 

    - The terminal box of the control circuit is attached to the front part. 

    - A draw-out rail guide is tremendously improved for an easy draw-out. 

    - It is equipped with an intelligent protection function, a function to select the high-precision setting and 

      a reliable power supply. 

    - Its reliability is improved using the meter and applying the highly-precise current detecting circuit.
