Moulded Case Circuit Breaker (MCCB) Review: Guide to Choosing the Right One

Circuit breakers are basically essential safety devices that help protect electrical systems from short circuits and overloads. Indeed, there are many types of circuit breakers on the market but they all do not give the same level of protection. One of the safest and most reliable options you can consider is the Moulded Case Circuit Breaker. In this article, you'll find more details about it, why it is the best, and features to consider when choosing one.

MCCB is a specialized type of an electrical protection device. It is used to protect your electrical system from overloads and short circuits thanks to its temperature sensitive features. With a current sensitive electromagnetic device, the MCCB will provide the trip mechanism for isolation and protection purposes. 

What happens is that the device automatically cuts the power supply anytime there is an overcurrent or fault situation. This ultimately helps prevent any damage to your electrical system. MCCB also features a molded case which helps keep the internal components safe from damage. The moulded case still helps keep the breaker cool by dissipating heat. 

Reasons to Consider Using Moulded Case Circuit Breaker

There are various benefits that set MCCB apart from other conventional circuit breakers. These include:

Enhanced dependability

With MCCB, you should expect your equipment and people to be safe from overcurrent, short circuit, and ground faults. They're also easy to maintain and have almost zero oversight.

Handle faults and high inrush current easily

This ability makes them operate nonstop basically under extremely challenging situations. In fact, this is a combined feature that makes MCCB the only sensible options for industrial operations. 

High Current rating

This feature gives MCCB an extra advantage compared to other options. They simply act as primary surge protective devices especially in the distribution panels. Some models still feature arc extinguishers. All of these features divert current arcs to enhance the durability of the breaker. 

Versatility

The good thing about MCCB is that they can be used to protect a wide variety of electrical systems. This includes everything from generators and motors to capacitor banks and welding machines. 

Applications of Moulded Case Circuit Breaker

The best part about MCCB is that you'll find them in different industries and settings. You may typically not see them because they work behind the scenes but they play a major role in ensuring the job sites run smoothly. Here are a few areas where MCCB are applied:

Industrial plants: Molded case breakers are commonly found in industrial plants. Several factories and fabrication lines rely on high-power equipment. The switches, motors, and heaters use thousands of amps of current. Therefore, MCCB plays a great role in keeping workers and machines safe. 

Improve environment in commercial areas: MCCB are also used in large retail warehouses and centers to either offer high voltage lighting or HVAC systems.

Residential sector: MCCBs offer strong protection for all electrical panels. The major task of these devices is to ensure homes are safe because as people adopt renewable sources of energy, like solar energy, then moulded breakers will be required. 

How to Choose the Right Moulded Case Circuit Breaker

Of course, while a moulded case circuit breaker is the best option, not all the available options are perfect for every job. Therefore, you will need to choose the right one based on the task ahead. So, what should go in your mind when making this crucial decision? Here are the factors you need to consider.

Electrical load

You should start by calculating the electrical load so that you are sure that the circuit breaker will be able to protect the system. It is important to remember that some systems can draw more power, of course under specific circumstances. The rule of thumb should therefore be to leave yourself room for error. 

Installation environment

Evaluate the whole installation environment. This includes conditions inside breaker panels, wiring runs, and conduits. You need to note that the MCCB you select must be able to withstand different humidity levels and temperatures. This is especially important in large areas like warehouses. 

Breaker specifications

The last thing you need to consider is to match the circuit breaker's specifications to the intended job. Check out the product page or industrial drawings to learn more about the breaker's terminal layouts, form factors, and sizes. 

Conclusion

MCCBs are indeed an essential component of electric safety and reliability. However, make sure that you choose the right breaker because different options have varying capacities. Once you understand what you need, proceed and make an order. For more information about MCCB, visit www.w9electrical.com or send an email to nicy@w9-group.com.
