Miniature circuit breakers protect electrical circuits from damage caused by overload or short circuit via the protection of thermal type trip and magnetic trip. 

MCB
Entek's MCB - KB

Features

  • 6kA & 10kA breaking capacity: These MCBs have a high breaking capacity throughout the range. They operate on current limiting principle ensuring extremely low let through energy under fault conditions.
  • Trip free mechanism: The MCB trips positively even when it's locked in on position.
  • Terminal Design: Double function terminal design for accepting both busbar and conductors simultaneously.
  • Safety terminals: The terminals are touch proof ensuring maximum operator safety against accidental contact (IP20 of protection).
  • Uniform components profile: The MCBs have a uniform profile and can be connected through pin type & fork type busbars. Bottom terminal for fork type busbar is isolated between the poles.
  • Accessories: Common modular accessories like Shunttrip, Motor mechanism, Undervoltage release and Auxiliary contacts ensure flexibility.
  • Energy saver: The watt loss of the MCBs is extremely low providing valuable savings over its entire lifecycle.
