Fuses

BK/PCB-1-1/2 is a type of fuse. Fuses are a protective device designed to blow when an overloaded or short-circuited circuit increases the current beyond the safe level of the fuse. Fuses are used in electrical systems to de-energize a circuit in case of a short circuit or overload, which prevent damage to the electrical system, as well as serious injury to users of the system.

Application Field

BK/PCB-1-1/2 is designed for circuit protection in a broad array of applications. It is widely used in various electronic and electrical components in various industries, such as consumer electronics, industrial control, domestic appliance, military, aerospace, railway, chemical, power equipment, automation etc. It can also be applied in various safety protection, such as insurance device, tripod device, compensator.

Working Principle

The working principle of BK/PCB-1-1/2 is divided into two parts：when normal and abnormal. BK/PCB-1-1/2 is a type of current-limiting fuse, which means it only allows a pre-set amount of current to go through the fuse. When the current increases beyond the safe level, the internal resistance will increase to limit the current and protect the circuit from damage.

When the current reaches its threshold level, the fuse wire will heat up and eventually melt due to the increased resistance. As a result, the fuse will be over-currented and the circuit will be de-energized, creating an open circuit. This interruption stops the electrical current from flowing and prevents any further damage.

In the event of an abnormal situation like overload or short circuit, the fuse will still react to the increased current flow. However, the increased current will quickly cause the internal resistance to become too high, melting the fuse wire and shutting down the circuit, which helps to prevent further damage to the circuit by breaking the circuit.

Advantages

Using BK/PCB-1-1/2 has many advantages. Firstly, it is a low cost solution for protecting circuits. Secondly, it can withstand high currents and will not be damaged easily. Thirdly, it is reliable and quick to respond in case of an overload. Finally, it is simple to use and maintain.

Conclusion

BK/PCB-1-1/2 is a type of fuse designed for circuit protection in a broad array of applications. It is a low cost, reliable and quick to respond solutions for protecting circuits. The fuse is designed to de-energize a circuit in case of a short circuit or overload, which prevents damage to the electrical system, as well as serious injury to users of the system.
