Fuse

For many professionals, fuse groups also have many desirable properties. As mentioned earlier, compared to circuit breakers, they are particularly cheap. They are very simple, easy to install, and in most cases, only a few bolts are needed to install themFuseQuickly connect to the common panel as shown in Figure 2. Wires are usually connected to integral screw type terminal blocks. In addition to its mechanical simplicity, the electrical flexibility provided by fuses may also be an important asset, especially when using unique circuits. In most new designs, the current requirements of the circuit can be strictly estimated, but various unforeseen situations may occur that could blow the originally specified fuse. In this case, the selected fuse can be quickly replaced for another unit that is more suitable for the application. A good example is a machine with high surge current. The specified original fuse may be sufficient to meet the operating current requirements, but it may melt each time the circuit is powered on. The fuse group enables technicians to quickly correct situations with the minimum cost of a few new fuses. Just replace the fuse with a delay fuse or slow fuse with the same rated currentFuseThe problem can be solved immediately. If a circuit breaker is initially installed, this situation is difficult to correct. In this case, the circuit breaker must be removed and replaced with a brand new device that matches the rated value and conditions. The costs associated with such changes reflect the workload of installing new crushers and dismantling old equipment to replace them with new ones.

Fuse or circuit breaker

The main disadvantage of fuse groups is their exposed electrical connections. If it is a larger snap in fuse, the socket clip should be exposed and closely adjacent to the other side of the circuit. When opening the casing containing the fuse box, these sockets will expose technicians to live circuits. Many power disconnect switches with built-in fuses are specially designed to eliminate this danger when turning off the power. It is always recommended to use a special set of insulated fuses when replacing larger fuses, as shown in Figure 3. However, at critical moments, ordinary technicians will bear a lot of pressure to ensure the normal operation of the equipment. If they are unable to use the fuse puller at any time, they may resort to safer methods to place the fuse and secure a new one. These improper practices have no future and will ultimately lead to electric shock incidents.
