Among various electrical control devices, which are installed for home use, commercial, and industrial electric systems, MCB  (Miniature Circuit Breaker) is one of the most important devices for protecting electrical circuits. The MCBs are safety electrical devices used to effectively isolate the electrical circuit when it gets overloaded or develops a short circuit to avoid damaging the wiring alongside other electrical apparatus. Biocon Electric India is the best company that offers high-quality MCB. 

What is an MCB?

An MCB is a type of Residual Current Circuit Breaker that is used to protect the circuit from the effects of excessive current flow, normally causing overcurrent due to overload or short circuit. The MCB switches off as soon as the current in the circuits rises to an agreed level, thereby protecting the circuit against fire outbreak, damage to equipment, or even electrocution.

Types of MCBs

MCBs are of many types, categorized by their tripping modes. These are determined by the time it takes for the MCB to trip under overload conditions:

1. Type B MCB: These MCBs operate at the current level which is three to five times the rated current. They are basically employed for lighting and domestic uses where the load is comparatively constant.
2. Type C MCB: These MCBs usually operate when the current getting through them reaches five to ten times its rated current. It has a current rating of 10-125A and is used where there is probable temporary overload as in industrial areas such as; motors and machinery.
3. Type D MCB: These MCBs are so made that they trip the moment the current operating on the conductor reaches 10 to 20 times the rated current. Type D MCBs are designed for applications that have high power loads such as transformers or loads with high inductive, including high current circuits.
4. Type K and Type Z MCB: These are relatively rare types of MCBs used for specific situations where accurate protection is required. They provide shorter travel time and are commonly used in assorted sensitive equipment.

MCB Sizes

MCBs can be categorized by size and their current rating depending on their usage and rating. The typical standard sizes of MCB cover between 6A and 63A of electricity current for common use in homes and business entities. But there is MCB that is equipped to cater up to 250A which is used in industrial and heavy usage areas.

The proportional features that should be considered when choosing the right MCB size include; the current rating of the circuit, the electrical load type, and the possible fault currents. They become easily tripped if down-sized, yet, if up-sized, they would compromise the safety of users.

Functions of an MCB

The primary purpose of an MCB is to afford the electrical circuits in a building or establishment protection from overload and short circuit current. However, MCBs serve several other purposes as well:

1. Overload Protection: MCBs prevent the wiring and related equipment from the risks associated with persistent overloading. In the case of excess current it activates, breaking the circuit as recommended by the rated current.
2. Short Circuit Protection: The MCB trips to a low value whenever there is a short circuit and switches off the circuit almost immediately to prevent any risks of fires, or damage to the wiring or the appliances.
3. Safety and Convenience: Compared to ordinary fuses, MCBs are more convenient as well as safer because they can be reset rather than replaced when tripping.
4. Efficiency: The use of current-day MCBs by Biocon Electric India protects electrical systems and circuits ensuring optimum performance without frequent reclamations.
