Earth Leakage Circuit Breaker : Circuit, Working, Types, Differences, Advantages & Its Applications

January 25, 2024 By Wat Electrical

Earth Leakage Circuit Breaker

The flow of current from the live conductor to the earth throughout an unintended lane is known as earth leakage. So it may supply in between their poor insulation (or) throughout a person’s body & cause electrical shock. The effect of this electrical shock causes damage to a device or a person if the leakage current goes beyond 30mA. So, protection devices like ELCB or earth leakage circuit breakers are used to separate the power source whenever … [Read more...]

January 5, 2024 By Wat Electrical

Miniature Circuit Breaker or MCB

Protection is the main concern while choosing any electrical device or appliance because when the power varies or excess current supplies, then it causes harm that results in a short circuit or an overload. So, it is necessary to integrate a device as a protection element to give over current protection to the device. The most common safety device used for protecting the circuit is a fuse which includes a metal wire/strip that dissolves whenever an … [Read more...]

Circuit Breaker : Circuit, Working, Classification, Differences & Its Applications

August 18, 2023 By Wat Electrical

Circuit Breaker

The first compact commercial circuit breaker was launched by Stotz in 1923 which combines both the thermal & magnetic protection functions. After that, his team developed a circuit breaker device to replace a fuse. This device has a component, once it is heated it will enable a disconnecting device and once it is cooled, then it is turned on again. There are many companies that have been developing circuit breakers continually which range from … [Read more...]

July 25, 2023 By Wat Electrical

Vacuum Circuit Breaker Construction

A circuit breaker is one type of electrical switching device used to control & also protect the power system, either automatically or manually from any harm occurred by short circuits or overload. The main function of the circuit breaker is to obstruct the flow of current once the protective relays notice a fault like electrical fires, shocks, and the electrocution risk. These are classified into different types based on different factors, location of … [Read more...]
