Circuit Breakers and Electrical Fuses

In a circuit breaker, the live wire and the neutral wire are wound around iron cores in opposite directions. And it is working by comparing the current leaving the appliance through the neutral wire and the current entering the appliance via the live wire

Circuit breakers are different from electrical fuses. If the appliance is working properly, means all the electrical current entering the device via the live wire leaves the device through the neutral wire, and the magnetic fields generated around the iron cores cancel out. In the event of a fault, some of the electric currents will flow through the earth wire or in the absence of earthing through the body of the user.

Circuit breakers are important in a power supply system. This makes an imbalance between the current coming to the appliance through the live wire and the current leaving through the neutral wire. Residual current is the difference in electrical current. The meaning of these differences is the decreased electrical current in the neutral wire has a weaker magnetic field associated with it than the live wire.

The two magnetic fields don't balance out and therefore the iron pivot is interested in the live wire and the contacts are disconnected breaking the circuit. Residual Current Circuit Breakers have the advantage of being sensitive and really quick reaction time making them safe.

An electrical fuse is an electrical component that is placed in an electrical circuit for protection against electrical faults such as a current surge. We can see the fuses in every residential and commercial building. Because it is an essential part of safety devices.

An electrical fuse can protect us from unexpected incidents. An electrical fuse is an electrical wire. It is enough thick to permit the required current for the device to pass through it, Also it is enough thin to melt and break the circuit if too many current flows.
