8~65kA 4 Pole MCCB Circuit Breaker Reliable Performance High Breaking Capacity


GENERAL


STS3 Moulded case ciecuit breaker is suitable for circuit AC 50HZ/60HZ, rated voltage up to AC 660V,rated operating current to 630A.It features normal structure,reliable performance,compete accessories & high breaking capacity, used foe power distribution and protecting the circuit and electrical equipment against overload and short circuit. It complies with standard of IEC 60947-2 and GB14048.2


Main Functions

  • Protection against overload – currents above the rated value that last longer than what is normal for the application.
  • Protection against electrical faults – During a fault such as a short circuit or line fault, there are extremely high currents that must be interrupted immediately.
  • Switching a circuit on and off – This is a less common function of circuit breakers, but they can be used for that purpose if there isn’t an adequate manual switch.

The wide range of current ratings available from molded-case circuit breakers allows them to be used in a wide variety of applications. MCCBs are available with current ratings that range from low values such as 15 amperes, to industrial ratings such as 2,500 amperes. This allows them to be used in both low-power and high-power applications.
