Question

Which are the devices now replacing the electric fuse?

Answer 1

Answer:

Answer:The device used these days in place of the fuse is MCB (Miniature Circuit Breaker). It turns off automatically when large current (larger than the safe limit) is passed through it. Magnetic tripping is the most common principle on which MCB works; it uses magnetic force generated through the current. It has many advantages over traditional fuses

Answer 2

Explanation:

Fuses and Circuit Breakers

A fuse or a circuit breaker automatically disconnects a circuit from the electric power the moment more current is drawn than its design allows. Electrical codes require one or the other to be installed at the point where power first enters a building. The electric supply to a home is usually divided into several circuits, each with its own fuse or breaker, of a rating appropriate for the thickness of the circuit's wires. That way, if the power is interrupted in part of the home, the rest of the home stays connected.
