BK/GLX-1/2 Application Field and Working Principle

Fuses are simple but highly effective forms of overcurrent protection. Suitable for a wide variety of electrical installation applications, fuses provide effective overload protection and isolation, by using two alloys to perform an action when a fault occurs. As a result, a fuse prevents a current flow from one conductor to another by opening the circuit, and thus provides a significant safety benefit.

For high voltage applications, the BK/GLX-1/2 range of fuses provides a reliable means of protection. This type of fuse operates in a current-limiting mode and has a rated breaking capacity of at least 20 kA. It can also withstand an impulse withstand voltage of at least 80 kV.

The BK/GLX-1/2 range of fuses is designed to be used as a power system protection device in a variety of switchgear system configurations. These include direct connected applications, three-pole fuse switch devices, and busbar current-limiting fuses, depending on the application requirements. As such, they are suitable for use in the protection of motors, transformers, rectifiers, capacitors, and other connected electrical equipment.

In operation, the BK/GLX-1/2 fuse uses two alloys to provide overload protection and isolation. The fuse is made of two contact pieces connected with a conductor. The two contact pieces are usually made from different metals with different melting points and electrical conductivities. When an overcurrent is detected, the lower melting point metal quickly melts and opens the circuit, thereby preventing any further current flow. This quick action prevents damage to the electrical equipment and provides a safe environment for users.

The BK/GLX-1/2 range of fuses also includes a range of fuses specifically designed for photovoltaic systems. These include the BK/GLX XI2000/M/I/X, which provides a four pole configuration suitable for use in photovoltaic systems. This type of fuse allows for a deferred operating time, which provides additional protection for the photovoltaic system and ensures that overcurrents are detected before damage can occur.

Overall, the BK/GLX-1/2 range provides a reliable, safe, and cost-effective solution for many overcurrent protection applications. Their applications and benefits can provide an extra layer of protection for electrical installations of any size.
