MCB (Miniature Circuit Breaker) is a replacement for a fuse.
What MCB to use for lights?
Type B devices are generally suitable for domestic applications. They may also be used in light commercial applications where switching surges are low or non-existent. Type C devices are the normal choice for commercial and industrial applications where some degree of electrical inrush is expected.
What is the work of MCB?
A miniature circuit breaker (MCB) is an Electrical Switch which automatically switches off the electrical circuit during an abnormal condition of the network means in overload condition as well as faulty condition. Nowadays we use an MCB in a low voltage electrical network instead of a fuse.
What is MCB and fuse?
Fuse is an electrical device that self-destructs and stops the current flow in a circuit whenever the current exceeds the predefined value. MCBs are resettable circuit protection device that, on the occurrence of faults, stops the current flow in a circuit.
Which type of MCB is used in home?
The best-suited type of MCB for domestic appliances, where the current load is medium, is type C. Type C MCB trips off when the flow of current is 5-10 times more than normal. Type D MCB has a high resistance as they can withstand up to 10-20 times the current rate.
Which MCB is best?
List Of Top 10 Best MCB in India

What is a 16Amp MCB used for?
16amp MCB’s are generally used on dedicated Freezer Circuits, and Immersion heaters circuits in the home.
Why MCB is used instead of fuse?
MCB is more sensitive to current than the fuse. It detects any abnormality in the current flow and automatically switches off the electrical circuit. In the case of MCB, the fault zone of the electrical circuit can be easily identified. … MCB provides a better interface with the help of knob than a fuse.
Can MCB replace fuse?
Miniature Circuit Breakers (MCBs) are electromechanical devices which are used to protect an electrical circuit from an overcurrent. … Unlike a Fuse, MCB does not have to be replaced every time after a fault occurs and it can be reused.
How is MCB better than electric fuse?
MCBs are more sensitive to current than fuses. They immediately detect any abnormality and switch off the electrical circuit automatically. This prevents any permanent damage to electrical appliances and human beings. The MCB detects any excess current and breaks the circuit.
