Modular MCB Switch: The New Age Saviour

What is a modular MCB switch?

The MCB is a “miniature circuit breaker” with excellent overload & short-circuit protection. It has a magnetic switching system whose primary role is to monitor and impede the current during emergencies. A modular MCB switch protects appliances from short circuits and excess current, so they are used in domestic and industrial applications. 

It is an automatically operated electromechanical switch that protects an electrical circuit from overcurrent. It is more sensitive to current than a fuse and does not require replacement if there is a fault. It automatically switches off the electrical circuit if any abnormality in the current flow is detected. 

Nowadays, MCBs are preferred over fuses for various reasons. They are used in low-voltage electrical networks as they are more sensitive to excess current than fuses. 

Advantages of a modular MCB switch

Here are some of the advantages of using modular MCB switches:

• MCBs are the improved versions of fuses. They are safer than fuses and used in low-voltage electrical networks.
• MCBs are more sensitive to current as compared to fuses. In electrical appliances, a small damage can cause a short circuit. It causes fire or even electrical shock to the user. MCBs identify the abnormality in the current flow & turn off the electrical circuit automatically. 
• Fuses can cause permanent damage to electrical appliances & the users. They are not sensitive to faulty conditions as MCBs. Therefore, MCBs are used instead of fuses these days. They detect the excessive current & break the circuit. 
• MCBs allow quick power restoration than fuses. By only switching ON the operating nob, you can restore the power supply in MCBs. Fuses need to be rewired or replaced for power restoration. 
• MCBs are electrically much safer than fuses. 

Key features to consider before buying MCBs 

• Safety Terminals

You may be using high-quality MCBs and power cables, but if the electrician does not terminate them, they may lead to failures and accidents. Safety terminals in MCBs are the essential features that eliminate the possibilities of improper terminations and avoid hazardous accidents. 

• Cooler Operations

It is another essential feature of an MCB that keeps it cool while in operation. During the summer, the temperature in India reaches up to 50 °C. The temperature inside MCB is much higher when in operation. With a passing current, it becomes critical to keep it cool. 

• Large Cable Terminations

This feature helps with proper termination, which is essential for ensuring the reliable functioning of the MCB. The cables are made from copper or aluminum with a thickness of around 35 mm2. 

• High-Quality MCB Enclosure

What is the point of having an MCB if it gets overloaded easily and catches fire during a short circuit? A high-precision molded thermoplastic material is used for good-quality MCBs.
