BK/GKJ-30

BK/GKJ-30 fuses are commonly used for circuit protection in industrial control, motor drive and power control applications. This type of fuse is an overcurrent protection device that uses a fuse link element to operate when current exceeds the maximum specified rating.

The BK/GKJ-30 fuse has a break point contact design. This ensures that the fuse blows in case of an overload and offers high performance when it comes to disruption of electrical flow. The design also ensures that the fuse will open safely in the event of a short circuit. The operating temperature range for these fuses is between -55°C and 125°C.

The working principle of the BK/GKJ-30 fuse is simple. When current flows through the circuit, the electrical resistance of the fuse element heats up. If the current level in the circuit is the maximum design value the fuse link will eventually heat up to a point where it melts and breaks the circuit, thus protecting the circuit from overload or short circuit. After the fusing has occurred, the fuse must be replaced with a new one.

These fuses are designed to provide protection from overload and short circuits without requiring extra safety devices. They are commonly used in motor drives, motor protection, and other power control applications. They are extremely reliable and cost effective solutions for overcurrent protection.

In order to ensure that the BK/GKJ-30 fuse is correctly matched to the circuit, it is important to use fuses that have the same rating as the circuit. Overvoltage protection should also be taken into consideration, as this can prevent unnecessary fusing of fuses. Finally, it is important to ensure that the fuse is not overloaded, as this can lead to dangerous levels of current.
