A fuse might be a bit cheaper and the form factor may smaller if size is an issue. If the fuse blows on a regular basis it will of course end up costing more and will be more inconvenient to replace.

Circuit breaker tripping affects via power failure to all equipment connected to it.
Fuse ratings are closer to the actual current of the device being protected, they are not affected by ambient temperature as breakers are. They act faster than a breaker and when sized properly provide more protection for equipment and personnel.

What one is better fuse or circuit breaker?
IMO it would be because the circuit breaker has the possibility of going bad and not working (allowing a short to move through the device), but fuses blow (cause a break) no matter what if shorted.
What do circuit breakers and fuses have in common?
Both fuses and circuit breakers cut off a circuit from its power supply when the total current through the circuit exceeds the current rating of the fuse or circuit breaker, usually due to a short to ground or overloading of the circuit. Both use materials that respond to heat.
What are the disadvantage of a circuit breaker or a fuse in a circuit?
The only ones that could affect that decision to put one in is if you're planning on smoking or blowing-up that item in the circuit, or the hassle of changing a 20 cent - 5 dollar item instead of the more expensive item.
Why is it important that homes have circuit breakers?
Fuses and circuit breakers are meant to protect your home's wiring from the heat generated from fault-currents and over-currents. Over-currents happen when you exceed the amperage the fuse or breaker is rated for over a period of time (IE: drawing 20 amps on a 15 amp circuit breaker). When this occurs a fuse or circuit breaker will open the circuit so the wiring in your home will not be damaged. Over-currents happen when electricity finds a path, other than the one intended, to ground. When this happens there is very little resistance to slow the flow of electricity and the amperage through the circuit can exceed the fuse or circuit breakers rated capacity by several hundred times . These type of faults cause the fuse or circuit breaker to open the circuit very quickly.
Why does a fuse blow or circuit breaker trips?
Both devices are safety measures for the electrical circuit. The home fuse is a glass affair with a burnable core. If the core melts, the circuit opens. The circuit breaker does the same thing, but is a "reset" device, meaning that it can be used over and over again. The fuse is replaceable, but not "reset-able." Both systems are used in modern homes, but the fuse system is being replaced by the circuit breaker system.

What is the advantage of a breaker over a fuse when used in your home?
A fuse is a one-time device; once it is used, it is no good. A breaker can be reset.

Advantages and disadvantages of fuses?
Advantage: a fuse is guaranteed to pop only when too many amps are pulled, unlike a circuit breaker that may be "accidentally" turned off by some practical joker. Disadvantage: You must have spares on hand (or go buy them when needed) unlike a circuit breaker which can be reset over and over.
How the circuit breaker differ in its function from combination switch fuse unit?
The function is the same in that they both are designed to remove an over current situation by opening the circuit. A tripped breaker can just be reset. A blown fuse needs to be replaced.

The first measure you should take to help prevent damage against electrical problems is to do what to the circuit?
Protect the circuit with an OCPD, an over current protection device, such as a circuit breaker or fuse.
What are the advantages of a circuit breakr compared to a fuse?
one primary advantage is that when a breaker trips you just reset it and go. When a fuse blows you have to replace it if you have one on hand. the real question is what are you trying to protect the the over current protective device? (fuse or breaker) each of these devices have a unique curve that explains how they will react to a fault condition. the time it takes for the device to trip is typically critical in deciding which to use.
What happens if you over power an electrical circuit?
fuse blows, breaker trips, wire burns. if the latter is in your house, a smoke alarm is disireable.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
