In the market today, several different circuit breakers are available, including MCCB, MCB RCCB, ELB etc. But all of them serve different purposes and are used in different settings. For example, both MCB and MCCB panel boards are types of circuit breakers, but their function and purpose are very different. Many people are familiar with the terms MCB and MCCB, but they might not know the difference between the two. Moreover, some people might not be aware of their basic functions. In this blog, we will look at the basic definition as well as the differences between these two types of equipment.
What is MCB?
An MCB is a protective device designed to protect electrical equipment against current overload. An MCB, or micro circuit breaker, is an automated electrical device that protects an electrical circuit from damage caused by excess current, typically generated by an overload or short circuit. It interrupts current flow when it detects an electrical fault.
What is MCCB Panel Board?
Moulded Case Circuit Breaker is an abbreviation for Molded Case Circuit Breaker. When the load current exceeds the limit of a small circuit breaker, this form of the electrical protection device is used. It protects against current overload and short circuits. It can be used for greater current ratings and fault levels, even in household applications.
The Difference Between MCB And MCCB Panel Board
The main difference between these two pieces of electrical equipment is their capacity. The MCB, with a rating of fewer than 100 amps, does not have an adjustable trip feature. As a result, MCBs are typically used in low-current circuits.
For further clarification, you can refer to the table below:
MCB | MCCB Panel Board |
MCB stands for Miniature circuit breaker | MCCB stands with moulded case circuit breaker |
MCBs are utilised for low-energy applications such as small electronic circuits or house wiring. | MCCB panel board is employed in areas with significant energy demands, such as high-power equipment in factories or for commercial purposes. |
The maximum rated current is 125 amps. | The maximum rated current is 1600A. |
In the case of MCBs, trip characteristics are fixed and cannot be adjusted | In the case of MCCBs, trip characteristics can be adjusted |
They are best suited for domestic use | MCCB panel board is best suited for industrial and commercial use |
Conclusion
Circuit breakers are used in buildings to provide energy and it increase safety. They take precautions to avoid fire hazards or other electrical problems by cutting off current flow when they detect a short circuit or an overload. Therefore, making ties with a reliable service provider is crucial to ensure you get the best possible product quality.
