What Are The Benefits of Installing Miniature Circuit Breakers?

MCBs or miniature circuit breakers are used in most residential and commercial buildings because of the level of safety and protection they provide. They are so important that they have become a must-have. They provide protection to both your appliances and to you against electrical faults and shocks, respectively. Find out the key features of MCBs and their advantages over the conventional fuse.

How Does an MCB Work?

Whenever there is excess current flow through a circuit, it can cause damage to your appliances. This can also cause harm to people in the building through burns or electric shocks. The miniature circuit breakers can detect the excess current and instantly break the circuit. In the past, the fuse was used to handle this function. The MCB is more reliable, safer and convenient.

The mcb changeover switch can be used to protect against current overload and also as a regular ON/OFF switch. It is connected with the current load in series and provides protection against a wide range of conditions including:

• Current overload
• Voltage fluctuations
• Fault in the circuit or appliance

Advantages of MCB Over Fuse

There are many advantages of installing the power distribution board in your building instead of using the conventional and unreliable fuse. Some of the most important advantages include the following:

• MCB has higher level of sensitivity to electric current fluctuations than fuse. It can detect the slightest variations in current flow and switch off the flow if the variation is abnormal.
• When you use miniature circuit breakers, it is easy to identify the zone or room with the faulty electric circuit. When you check the board, the switch with the off position will help you identify the zone. When you use a fuse, it is not possible to locate the room/zone with the faulty circuit. You will have to check the entire building to find where the fault has occurred.
• Another advantage of using a metal distribution board is that it makes it easy to resume the power supply to the room or zone. Once the fault has been fixed, you can resume the supply by pushing ON the knob. With the conventional fuse, you will have to replace the burnt-out fuse wire.
• MCBs are much safer than the fuse. There is no risk of coming in contact with the live wire. All you have to do is identify the fault, fix it and switch the knob ON.

With the mcb changeover switch, all you have to do is the switch the knob ON to resume the power supply. In the case of a fuse, you will have to replace the wire every time there is a fault. Over the years the cost of replacing wire can increase significantly. MCBs are also quick to work with. Once the electrical fault has been fixed, you can instantly resume the power. They are also more reliable because they instantly cut-off the current flow on detection. The fuse is not as reliable and can also result in causing damage to costly appliances. Thus, there are many reasons for installing an MCB in your building.
