Electrical fuses protect circuits by interrupting the flow of electricity when it exceeds a safe level, preventing overheating and potential fires. They contain a metal wire that melts when too much current passes through, breaking the circuit. This quick disconnection helps safeguard appliances and wiring from damage and reduces the risk of electrical hazards. By ensuring that excess current does not reach critical components, fuses play a vital role in electrical safety.

How do fuses and circuits breekers help to protect us?

Fuses and Circuit Breakers act as a control mechanism to the flow of current in electrical circuits. A fault can develop in an electrical appliance without us noticing and this is where circuit breakers and fuses help in automatically disconnecting the faulty appliance from the power source. Most electrical faults resulting excess heat generation which in turn cause fires. Electrical shock can also be prevented by special types f circuit breakers called Earth Leakage Circuit breakers (ELCB). These breakers operate whenever there is an earth leakage protecting humans.
