BK/GLD-2

The BK/GLD-2 fuse is an advanced technology fuse designed to provide a high degree of protection for medium-voltage systems. It is commonly used to protect motors, transformers, cables and power cables. This fuse offers several advantages over common and existing fuse designs.

BK/GLD-2 fuses are designed to provide a high level of protection to electric systems by providing a fast reaction time and high accuracy in responding to overloads and short-circuiting. It also provides a very small time lag when switching from clear state to short-circuiting state. This helps in preventing failures and loss of equipment in areas where delays due to thermal and mechanical limits can cause serious and costly damage.

The design of the BK/GLD-2 fuse makes it particularly suited to medium voltage applications. It uses a very small volume of material, making it exceptionally compact and lightweight. This allows for easy installation and a lower cost. It is also designed with an arc-gap feature that helps prevent arcing at higher levels of current, reducing the chances of motor failure or damage.

The working principle of the BK/GLD-2 fuse is similar to that of other conventional fuses. It operates on a time-delay basis: when an overload or short-circuit occurs, a current passing through the fuse causes the filament to heat up. This heats up the liquid crystal material inside the fuse and triggers a thermal switch, which trips and breaks the circuit.

The reset of the fuse is provided by a reset latch, which works by releasing a reset spring. This spring helps the fuse return to the open state once the high current is removed. The reset latch can also be reset manually by using a manual release switch.

The BK/GLD-2 fuse also has a safety feature that prevents too much current from flowing through it. This safety feature is known as the overload release mechanism. It is designed to trip the fuse off when overload currents reach dangerous levels. The overload release helps protect the load from excessive amperage or high-frequency currents.

The BK/GLD-2 fuse has been designed for safety and efficiency. Its unique design allows for device protection with high levels of accuracy and responsiveness. With its low profile and lightweight design, it can be easily installed, making it an ideal choice for medium voltage applications.
