What is MCCB ?<\/h2>\n<\/div>\n<\/div>\n

\n

\n

\n
• Molded case circuit breakers are a type of electrical protection device that is generally used for a wide range of voltages, and frequencies of both 50 Hz and 60 Hz.<\/li>\n
• The main distinctions between molded-case and miniature circuit breaker are that the MCCB can have current ratings of up to 2,500 amperes, and its trip settings are usually adjustable.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n

  MCCB has three main functions:<\/h2>\n<\/div>\n<\/div>\n

  \n

  Protection against overload<\/h2>\n<\/div>\n

  \n

  \n

  \n
  • Currents above the rated value that last longer than what is normal for the application.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
    \n

    Protection against electrical faults<\/h2>\n<\/div>\n

    \n

    \n

    \n
    • During a fault such as a short circuit or line fault, there are very high currents that must be interrupted directly.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
      \n

      Switching a circuit on and off<\/h2>\n<\/div>\n

      \n

      \n

      \n
      • This is a less common function of circuit breakers, but they can be used for that purpose if there isn\u2019t a suitable manual switch.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
