Circuit breaker can achieve short-circuit and overload protection, but not the same principle, fuse factory outlets, it is implemented through the current circuit breaker bottom magnetic effect (electromagnetic release), by thermal effect of current overload protection (not blown, more without replacement devices). Specific to the practice, when the circuit of the electrical load for a long time closer to the fuse-load, the fuse will gradually heated until the fuse. Like said above, the fuse is a result of interaction of current and time to play on the line to protect the role, it is disposable. The current in the circuit breaker is suddenly increased, exceeding the load circuit breaker will automatically disconnect, it is a momentary current increase circuit protection, for example, when the leakage is large, or short, or transient current great protection when. When identify the cause, you can continue to use the closing. As mentioned above, the fuse is a result of current and time interaction, and the circuit breaker, as long as the current one will trip over the set value, the time effect is almost not considered. Circuit breakers are commonly used in low-voltage power distribution components. Also part of the place is suitable for use fuses. Fuses melt jet is mounted in the insulating gas pipe from a solid material. The solid material can be gas or electric and anti-white board plexiglass materials. When the short-circuit current is passed through the melt, fuses price, then melt blown arcing, since the complex fuse, high temperature arc gas solid materials decompose rapidly produce large amounts of high-pressure gas, thereby ionizing the gas in the tube ends with an arc spray an issue of great sound and light, and extinguish the arc in AC current zero while breaking current. Insulating tube is usually mounted on an insulating stand, fuses, fuse overall composition. Sometimes the upper end of the insulating tube made of movable type, the breaking current drop immediately after disengagement, such jet drop fuse fuse known. Generally applicable to a voltage higher than 6 kV outdoor occasions. Fuses price, fuses, Xi'an by the Xi'an high Huayi power plant.
