Main Circuit Breaker for High Speed Train(MCB)
introduction of item
VITZROEM VTB is a product that safely interrupts extra high fault current that is generated due to a failure at an electric system during the operation of trains. It should be more resistant to severe vibration than the general circuit breakers since it is installed in the trains that run on the rail. The number of switching operation is 20 times more than the other circuit breakers and it is equipped with the durability too endure the switching operations of 250,000 times. It is a vacuum train breaker with the biggest capacity in the world and its performance was verified by KERI. Korea Institute of Machinery&Materials tested the anti-vibration function based on IEC61373 1-Type B.

Product Features

 1) It is successfully internationalized through a performance test executed by the local authentication organization.

  – It is a vacuum train breaker with the biggest capacity in the world and its performance was verified by KERI. Korea Institute of Machinery&Materials tested the anti-vibration function based on IEC61373 1-Type B.
2) It ensures the safety of operators by adopting a pressure switch.
  – It is designed to operate within the designated pressure range so that there is no problem in the operation of the circuit breakers depending on the pressure change inside the train.
 3) A filter is installed in the product to prevent pollutions and to improve the operational cycle and functions.
  – The Vacuum Interrupter being used is designed with sufficient amount of conducting capacity which led to a stable performance and high electrical life cycle.
4) The parts are sophisticated and compatible.
  – All the parts are manufactured from professional manufacturers abroad which include the main parts such as the regulator, pressure switch, auxiliary switch, relay and so on.
