Apa itu MCB Listrik dan MCCB
What are Electric MCB and MCCB, do you know the difference between the two products? For ordinary people, we often hear the two electrical devices, but sometimes we still misunderstand them. In this article, we will briefly discuss the two devices, hopefully it can help a little.
In this day and age, it is rare to see an area that does not use any electricity at all. Both in cities, as well as in rural areas, all have started to use electricity. If we talk about the use of electricity and its tools, there must also be an electrical panel. An electrical panel is a device that regulates and distributes electricity from a power source to electrical equipment at the facility.
If you've ever seen an electrical panel, surely you've at least seen a device that has a switch like the picture above. However, perhaps many of us do not know what a tool is and what it does. This device is called a Circuit Breaker (CB). The function of the CB itself is as a protection and circuit breaker in the event of an overload or short circuit. CB is very important because a malfunction of the CB can cause a fire.
CB itself has many types that can be adapted to consumer needs. In this article, we will discuss two types of CB, namely Miniature Circuit Breaker (MCB) and Molded Case Circuit Breaker (MCCB). Why are there so many types of CB? What's the difference between the two?

The first difference is the current rating. The current rating is the current consumption required by the device to operate. Electrical MCBs have a smaller current rating capacity, only up to 63 Amps. While the MCCB has a current rating capacity of up to 1000 Amps. So that the electric MCB is more suitable for use in tools with a small rating,
while MCCB is used for heavier equipment. The price of electric MCB is also cheaper than MCCB, this is because MCCB is intended for use on heavy equipment. From size, MCCB is also bigger.
Trip Level is the threshold current that passes through the CB that causes the CB to switch off. So, when the current through the CB exceeds the amount it should, then the CB will
automatically cut off the current. The amount of current that exceeds the actual number is what often causes fires in buildings, so the CB is important to function properly. In electric MCBs, the Trip Level cannot be set, while in MCCBs, the trip level can be set by the user as needed.
Interrupting Capacity is the limit of the current that passes through the CB before the CB is damaged. If the current exceeds the interrupting capacity limit, the CB will not function. MCCB has a higher value than electric MCB. MCCB also has the ability to
function in an under voltage trip condition (when the voltage is lower than the specified limit)
specified) and shunt trip (can cut current from an external source, not just because it exceeds the allowable current limit).
From the explanation above, it is clear that the MCCB has more features than the electric MCB. However, it is also necessary to pay attention to the needs of the users themselves. more MCCB
required at industrial and commercial levels. If you want to install a CB at home, an electric MCB is enough to carry out its functions.
