Miniature circuit breakers or MCBs are a must-have for all buildings. They help increase the electrical safety in your home or office while also protecting your electrical equipment. There are a number of benefits of installing these units in your building. This guide provides you all the reasons for having a miniature circuit breaker in your home or commercial building.

What is an MCB?

A miniature circuit breaker or MCB is an electrical switch which is automatically operated. It works to keep both humans and electrical equipment safe against electrical faults and shocks. Whenever there is some fault, electrical current exceeds a certain limit. This can damage your electrical devices. An MCB works by interrupting this high current and prevents any burns or damages to your electrical equipment.

It works by detecting the excess current flow and instantly breaks the circuit. When this occurs, you will see the respective area’s MCB button tripping. In doing so, miniature circuit breakers have replaced the traditional fuse. Fuses are still in use, but in settings where high voltage is involved. MCBs have become almost the standard in buildings where low voltage electrical systems are involved.

Advantages

The key advantages of mcb electrical systems are as following:

High Sensitivity: These modern systems are much more sensitive towards current than fuse. They work by detecting any abnormal changes in current flow. The moment such changes are detected, the electrical circuit is instantly switched off. The fuse cannot operate with this level of reliability.
Ease: Modern miniature circuit breakers are easier to use. You can easily resume the supply after fixing the issue. All it needs is to push the button back to the ON position. On the other hand, replacing a fuse wire requires some time. Another thing that makes this system easy to use is that it helps identify the zone where there has been a fault. This is not possible in the case of fuse.
Safety: The miniature circuit breaker is also safe to use compared to using the fuse. There is no risk of contacting any metal surface. On the other hand, the fuse has to be replaced manually.
Cost-Effective: When there is a case of tripping, there is no need to replace any component within the MCB. All you have to do is to fix the fault in the identified zone. When a fuse burns, it is required to replace it. This can increase the cost of maintenance in the long-term. Thus, an MCB is a one-time investment that saves you money over the long-term.

Thus, there are many advantages of using a miniature circuit breaker compared to the traditional fuse. It is much safer than manually handling the fuse wire. It saves you valuable time by instantly providing an indication as to which room or which zone has an electrical fault. You can check that zone and fix the problem to retain the connectivity. If you already don't have an MCB in your building, make sure to have one to ensure optimal safety and efficiency.
