MCBs
MCBs mean miniature circuit breakers. It is a switching device that protects an electrical circuit from short circuits or currents. Mainly MCBs help with the overload, which would lead to overcurrent. The advantages of MCBs are:
Advantages
-
MCBs are more protective of current than fuses and are better than a fuse.
-
It helps quickly against short circuits in the electrical system.
-
Since MCBs are reusable, they save on maintenance costs and replacement costs.
-
It is very easy to resume the supply.
-
It can be used easily as a circuit control switch when needed.
-
These circuit breakers are very reliable for electric power systems.
-
Handling MCBs is always safer than handling fuses.
-
The performance of miniature circuit breakers is better in case of earth leakage.
-
With the use of MCB, the faults in the circuit can easily be identified.
Disadvantages
-
The cost of buying an MCB is higher than that of a fuse.
-
Even the price of the MCB distribution board is higher than that of a rewirable fuse board.
-
There could be a risk of overloading the circuit due to someone who's not qualified to use it.
-
The metal strips within the MCB wear with age could cause the breaker's reaction time to slow.
MCCBs
MCCB is another type of circuit breaker that fully means molded case circuit breaker. This circuit breaker is a switching device used when the current load exceeds the limit of a miniature circuit breaker. The MCCB protects against overload and any faults related to short circuits and switching the circuits.
The advantages and disadvantages are:
Advantages
-
MCCBs are compact, so they don't take a significant amount of space in the inboard plan.
-
These circuit breakers are upkeep-free, which is why repeating costs are less.
-
They prevent the system from faulty situations and help with overload protection.
-
It's not very time-consuming to reset and switch on while it trips during the wrong conditions.
-
If you buy MCCBs or MCBs online, they have a wide range of options available to choose from.
-
The maintenance fee is very less or even free.
-
They are cheaper than ACBs
-
MCCBs are amazing for their working principle in commercial and industrial applications.
-
Adjustable current settings.
Disadvantages
-
MCCBs don't have the longest life span in electrical systems.
-
They are not suitable for domestic use.
-
High voltage applications can't help these circuit breakers.
-
If you want high-quality ones, they could get expensive.
-
You cannot operate it if you are not professional.
