BK/GBB-V-30-R

Fuses are widely used in electronic systems to provide protection for devices in applications ranging from controlling circuits to industrial equipment. They are designed to burn out at a specified current level, preventing current from exceeding safe levels for the components or circuits they protect. The BK/GBB-V-30-R fuse is one type of fuse that is commonly used in circuits because of its simplicity and ability to be changed quickly for different current levels. The following article will discuss both its application field and working principle.

Application Field

The BK/GBB-V-30-R fuse is a type of time delay fuse. It is often used in low voltage applications, such as motor controls, pumps, fans, and lighting. The BK/GBB-V-30-R fuse is designed to provide over current protection with a delayed response, allowing for the device to start up with high inrush currents. This time delay feature also helps to protect against short circuits, since the fuse will allow for a brief current overload. The BK/GBB-V-30-R fuse has a maximum PCB operating voltage of 32 volts and an operating temperature range of +70°C to -40°C. The fuse has an axial design and a body size of 6.3mm diameter x 32mm length for easy installation.

Working Principle

The BK/GBB-V-30-R fuse is designed to protect circuits and components from over current. It is a type of fuse that is sensitive to current only, meaning that it will respond to changes in the current, not changes in the voltage. The fuse has a fixed current rating, which is the point at which it will "burn out" and no longer allow current to pass through. The fuse operates by heating a metal member which becomes softer and eventually melts when more current is drawn. This interruption of the circuit prevents further increases in the current.

The BK/GBB-V-30-R fuse also has a time delay feature. This means that if a large amount of current is suddenly drawn, the fuse will act as a buffer and will not trip immediately. Instead, the fuse will “soak” or absorb the current for a certain amount of time before it trips. This provides a safety buffer and helps to protect components from catastrophic failures.

In summary, the BK/GBB-V-30-R fuse is a time delay fuse that is often used in low voltage applications. It provides over current protection with a delayed response, allowing for devices to start up with high inrush currents, as well as short circuit protection. The fuse also has a fixed current rating which helps to protect components or circuits from over current.
