We often hear the name MCB (Miniature Circuit Breaker) which is in every house. Many of us only know that this tool is related to electricity in the house. However, what are the actual uses, roles and differences with MCCB? For more details, there is some information in this article, hopefully it can help a little in understanding these electrical devices.
MCB (Miniature Circuit Breaker) and MCCB (Molded Case Circuit Breaker) are two types of circuit breakers used in electrical installations in homes or buildings. Both types of circuit breakers function to protect electrical installations from overcurrent and short circuits. Even though both of them have the same function, there are differences between MCB and MCCB. The following are the differences, functions and benefits of MCB and MCCB.
The difference between MCB and MCCB
Construction
MCBs are made of plastic and glass, while MCCBs are made of stronger and more durable materials such as metal.
Current breaking capability
MCB can cut electric current up to 100A, while MCCB can cut electric current up to 2500A.
Short circuit breaking capacity
The MCB has a lower short-circuit breaking capacity compared to the MCCB.
MCB and MCCB functions
The main function of the MCB and MCCB is to protect electrical installations from overcurrent and short circuits. Both also function to cut off electricity when there is a failure in the electrical installation, so as to prevent fires or damage to electrical equipment.
Benefits of MCB and MCCB
Prevent fire
Installing the MCB and MCCB can prevent fires from occurring in electrical installations. These two types of circuit breakers can cut off the electric current when an overcurrent or short circuit occurs, thereby preventing damage or fire to electrical installations.
Increase security
MCB and MCCB can increase the safety of electrical installations. The installation of these two types of circuit breakers can ensure that the electrical installation is protected from damage and fire which could endanger the security of the occupants of the house or building.
Extends the life of electrical equipment
Installing MCB and MCCB can extend the life of electrical equipment. With the protection of these two types of circuit breakers, electrical equipment will not be over-current or short-circuited, thereby extending the life of electrical equipment.
Reduce repair costs
Installing MCB and MCCB can reduce repair costs. With the protection of these two types of circuit breakers, electrical installations will be better protected from damage and fire, thereby reducing repair costs in electrical installations.
In choosing between MCB and MCCB, it is important to consider the required breaking capacity and the characteristics of the electrical installation used. Both types of circuit breakers can provide protection.
