What is the difference between the fuse and the circuit breaker?

Great energy overload can potentially destroy electrical equipment or cause fire in more serious cases. The fuse and circuit breaker are used to protect the overloaded electrical circuit by interrupting the continuity or flow of electricity. However, the way they interrupt the flow of electricity is very different. The fuse consists of a piece of metal that melts when overheating; The circuit breaker has an internal mechanism of the switch that is buried by a dangerous increase in electricity. Fuses are faster to interrupt the energy flow, but must be replaced after melting, while the circuit breakers can usually be simply reset.

How do fuses work

There are many different types of fuses for residential and commercial use, but the most common type is made of metal wire or fiber that is closed in a glass or ceramic and metal case. In the house, the fuse is usually connected to the central fuse box, where all the cabling of the building passes. When electricity flows normally, the fuse allows power supply PRto sit uninterrupted through its fiber, between circuits. If the overload occurs, the fiber melts and the flow of electricity stops.

Generally takes very little time per fuse type used in the house to melt, so any surge surge is quickly stopped. However, once the fuse is blown, it must be discarded and replaced by a new one. There are many different voltages and evaluation that process different electricity capacities, and the best circuit fuse is usually evaluated slightly higher than normal operating current.

How do circuit breakers work

circuit breaker with circuit works in one of two ways, with electromagnet (or solenoid) or bi-metal strip. In both cases, the basic design is the same: after switching on, the circuit breaker allows the electric current to switch from the bottom to the upper terminal via the solenoid or belt. When the current reaches dangerous levels, the magnetic force of the solenoid becomes so strong that the metalThe lever inside the switching mechanism is thrown and the current is interrupted. Alternatively, the metal strip bends, throws the switch and breaks the connection.

To reset the electricity flow after solving the problem, the switch can be easily switched on and re -connected. The circuit breakers are often found in the cabinet of individual switches called the circuit breaker. The simple switching action of circuit breaker circuit also makes it easier to turn off the individual circuit in the house if it is necessary to work on the cabling at this point.

Another use of the circuit breaker is the circuit (GFCI) outlet that works to prevent electrical shock instead of overheating. It works by breaking the circuit in the output if the current becomes unbalanced and can be reset by pushing the buttocks. This technology is particularly useful in bathrooms or kitchens, where the electric power plant is a risk due to the frequent use of electrical appliances near the water source.

advantages and disadvantages

fuse and circuit breaker with circuits have advantages and disadvantages, of nothingEach can depend on the situation in which they are used. Fuses are cheap and can be purchased from any hardware store. They also tend to respond very quickly to overload, which means they can offer greater protection of sensitive electronic devices. However, this rapid response may be a disadvantage, but if the circuit is prone to increases that regularly cause fuse blowing.

Fuses must always be replaced as soon as they are blown, which can be demanding in a darkened room or if the relevant replacement is not available immediately. Another problem is that Do-it-YourSelfer can mistakenly choose a fuse that has a voltage or current evaluation that is too high for its needs, which can lead to a tough-heated circuit. In addition, an electrical connection may be exposed to a fuse box that may be a danger to someone who does not follow the correct safety measures.

circuit breakers have many advantages, not least, how fast they canto tune. Usually it is clear which switch has buried and in most cases it can be easily reset. This is also safer for the average house owner, because there is no doubt about choosing the correct fuse rating and all electrical connections are hidden in the circuit breaker frame.

The disadvantage of using the circuit breaker is that it is usually more expensive to install and repair. Nor does the circuit breaker usually respond as quickly as the energy overvoltage fuse, which means that it is possible that the electronics connected to the circuit could be damaged by "passing" energy. It is also more sensitive to vibrations and movement, which can cause a switch trip for reasons unrelated to electricity overload.

Fuse and circuit breaker with circuits are not interchangeable for all power applications. For example, the fuse cannot be used in situations that require GFCI. Electricians are best qualified to determine whether the fuse system or circuit breakers are better for a specific electrical installation or upgrade.
