Why Should you install MCBs?

Any mishap due to over current, overload or short circuit can be really dangerous. Instead of waiting for an accident to happen, it is always better to prevent such mishaps by safeguarding your circuitry, appliances, and loved ones through adequate switchgear in advance. 

Earlier people used fuses to protect their electrical equipment and network on the whole. With technological advancement, MCBs emerged on the scene and replaced the fuses at least in domestic applications. And why not, these mechanically operated switches cum circuit protection devices work perfectly well to suspend power supply in circuits during overload and short circuits while keeping you safe and sound. Moreover, these can be reused even after interruption of the circuit, unlike fuses. More often, MCBs are commonly used in low voltage electrical networks. Let’s know how MCBs are advantageous to use.

Advantages of Miniature Circuit Breakers

Being sensitive to over current, MCB automatically cuts off the power supply during overload and faulty conditions. Unlike MCBs, a fuse is not that sensitive to the faulty conditions.

As the MCB trips, while breaking the supply of electrical circuits, the switch operating knob comes at OFF position which makes it easier to identify the faulty zone of the electrical circuit. 

However, in case of a fuse, the fuse wire needs to be checked by opening fuse grip or cutout from fuse base, for confirming the blow of fuse wire.

  • MCBs allow quick restoration of power supply

by just switching ON the operating knob. In case of a fuse, it needs to be rewired or replaced for restoring the power supply.

  • MCBs are safer than a fuse. 

Since MCBs offer improved operational safety and more convenience than the old-school fuse, MCBs are commonly used in low voltage electrical networks.

  • MCBs offer better protection against electrical faults

It is wise to invest in them. Their procuring cost could appear more at the outset, but the operating cost is much lesser. 

Factors to be considered before procuring MCBs. 

If you are about to procure MCBs then here are some key features to consider for ensuring maximum safety of property and human life.

  • Safety Terminals

You may have a really good quality MCB  and power cable running to it, but if your electrician fails to properly terminate the cable into its input and output terminals, it can lead to failure of the MCB and a hazardous incident. Safety terminals eliminate the possibility of improper termination as the cage guides the cable for systematic termination.

  • Large Cable Terminations

Cables terminating into an MCB made from copper or aluminum can be as thick as 35mm2 in the cross-section area. Large termination ports help in proper termination that is a must for ensuring the reliable functioning of an MCB during an incident.

  • Cooler Operation

India is a country with a varied climate. The summers could be excruciating where the outside temperature may reach upwards of 50 °C. The temperature inside an MCB with passing current can be even higher. So, it becomes critical for a good MCB design to feature an efficient design that cools the entire MCB unit while it is in operation. An MCB with grooves on the outer body will promote better air circulation inside when individual poles are placed adjacent to each other, cooling the overall switch operation.

  • High-quality MCB Enclosure

What is the point of an MCB having all the bells and whistles if it can’t hold its components in place and disintegrates or catches fire during a short-circuit or overload? A good quality MCB is usually made of high-precision molded thermoplastic material. It should possess flame-retardant properties having a high melting point, high dielectric strength, lower water absorption, and the ability to withstand high temperatures.
