What can be used to protect an electrical circuit other than a fuse?

Circuit breakers are devices that protect circuits from overload current conditions. They do the same job as fuses, but they are not destroyed when activated.

What other device could be used to protect a circuit instead of a fuse?

A Miniature Circuit Breaker is an electromechanical device designed to protect an electric circuit from overcurrent. MCBs are reusable where fuses are not. They are also much easier to use, with on/off switching for circuit isolation and are much safer as the conductor is housed within a plastic casing.

What are 3 types of circuit protectors?

There are two general categories of circuit protection: 1) Fuses 2) Electro-mechanical circuit breakers. Each has its advantages which will be discussed here. Fuses break down into three convenient categories —fast-blow, slow- blow, and semiconductor. Each responds to fault current in different ways.

What kind if device is a fuse?

A fuse is an electrical safety device that has the capability to protect an electric circuit from excessive electric current. It is designed to allow current through the circuit, but in the event that the current exceeds some maximum value it will open, severing the circuit.

What does a fuse protect against?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.

Can we replace a fuse by a piece of wire?

No, the electrician should not be allowed to replace the fuse in the house with a piece of wire. … A fused filament must have a low melting point such that it could melt and break in response to a large amount of current. Most of the wires have high melting points and hence a wire cannot be used to replace the fuse.

Can I replace a fuse with a higher amp?

CAUTION! Never replace a blown fuse with a higher-amp fuse. Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement.

Can I use a fuse instead of a diode?

If you want to make a decision on a replacement, you should check the current that the unit takes and the fuse in the circuit. If there is a 10 Amp surge, then you need a diode that can handle it. Attach your own fuse to the unit.
