Here we provide coordination chart link for required rating and model of MCCB.

• 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.
• 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.

• Currents above the rated value that last longer than what is normal for the application.

• During a fault such as a short circuit or line fault, there are very high currents that must be interrupted directly.

• This is a less common function of circuit breakers, but they can be used for that purpose if there isn’t a suitable manual switch.
