MCCBs ( Moulded case circuit breakers) are used for switching , protection and communication for electrical systems , motors , generators from fault currents in the range of 63 Amps to 2000 Amps.
is used for providing protection against short circuits and faults happening in electrical system.
MCCB is having some special characteristics over MCB. It
protects loads from over current, short circuit current and
earth fault protection. Moreover it is available in all
ranges (16A to 3200A).
?MCBB stands for “Molded Case Circuit Breaker”.
?Rated current in the range of 10-2500 amps.
?Thermal operated for overload and & Magnetic operation for instant trip in SC (Short circuit conditions)
?Interrupting rating can be around 10k – 200k amps.
?Suitable for high power rating and high energy i.e. commercial and industrial use.
?Generally, used where normal current is more than 100 Amps.
