MCB: Miniature Circuit Breaker
MCB Full Form
MCB full form stands for Miniature Circuit Breaker. A miniature circuit breaker is an automatic powered electrical switch designed to protect the electrical circuit from damage due to overload or short circuits.
Its main function is to interrupt the current flow after detecting a fault. Unlike a fuse, which is running once and must then be replaced, the circuit breaker can be reattached to resume a general surgery.
Initially, fuses were used instead of MCBs. The fuse needs to be replaced after a short circuit while the MCB is yet to be reset and it will start working. The MCB provides greater operational security and is easier to use. It detects an error by detecting an excessive amount of current in the circuit and breaks the circuit as quickly as possible.
Circuit breakers come in a variety of sizes, from small devices that protect large switch gears designed to protect high-voltage circuits to low-current circuits or personal home appliances that feed the entire city. The common function or fuse of a circuit breaker, as an automatic method of removing power from a faulty system, is often referred to as an over-crank protection device.
- MCBs are reusable and therefore cheaper than fuses.
- This provides a better interface using the knob.
- It is more sensitive to the present.
- Handling MCBs is much safer for humans as well as electronic devices.
- In MCB, the faulty wire is far from the original position which makes it very easy to detect faults.
