BK/S500-V-800-R Fuses Application Field and Working Principle

BK/S500-V-800-R fuses are fast-acting three-pillar fuses with a rated voltage of 500V and rated current of 800A. They have wide applications in an array of power distribution systems.

Application Field

BK/S500-V-800-R fuses are widely used in a variety of electrical applications such as distribution, protection of low voltage circuits, motors and capacitors, and other power distribution systems. They are capable of dealing with high inrush current, preventing overload and short circuit of electrical equipment.

In terms of motors, BK/S500-V-800-R fuses are often employed as the disconnecting device to protect the motor from being burn out due to frequent overload. They are especially suitable for three-phase motor due to their compact and efficient design.

In the power distribution system, these fuses are used as the electrical circuit breaker to protect the lines and equipments from overloading. They are capable of automatically disconnecting the circuit when the current is over the rated value, thus preventing the circuit from damages.

Working Principle

The working principle of BK/S500-V-800-R fuses is based on the fact that the current passing through the fuse wire is too high to be tolerated by the fuse wire itself. As soon as the current reaches the rated value of the fuse, the fuse wire will get overheated and ultimately blown out, thereby breaking the circuit and preventing the current from passing through.

The working principle of the fuse depends on two factors: the fusing time and the clearing time. The clearing time refers to the time taken after the energy input to the fuse wire, whereas the fusing time denotes the time it takes for the fuse wire to be blown out as a result of current overload.

In order to work effectively, the fuse needs to be carefully designed and manufactured so that the fusing time is less than the clearing time. This ensures that the fuse is triggered soon enough to prevent any damage caused by an overload of current.

Conclusion

By understanding the right application field and working principle of BK/S500-V-800-R fuses, their effectiveness in protecting low voltage circuits and motors from overload can be maximized. These fuses are an important part of any power distribution system\'s safety and protection while ensuring maximum efficiency despite voltage variations.
