Fuses are convenient, easy to install, and widely used in electrical and electronic systems. They provide a simple way to protect against over-current, short circuits, and other dangerous situations. GLD-1/2 fuses are specifically designed for medium-voltage applications and offer a reliable solution for protection.

GLD-1/2 fuses have a voltage rating of 8.3kV, are available in sizes from 250–1200A, and are suitable for short-circuit current ratings of up to 200kA. They feature low power loss, fast response times, high melting point, and an elongated design for superior arc-extinction capability. The fuse has two end caps - one red for the outgoing load circuit and one black for the incoming supply circuit. GLD-1/2 fuses are available in both tube and link versions, and are commonly used in medium-voltage distribution systems.

The two main components of the GLD-1/2 fuse are the holder and the element. The holder consists of two parts - an acid-resistant bottom with an isolator, and a checkered top with a fuse position indicator. The element is a cylindrical silver-plated spiral wire with an end cap. The fuse holder creates an arc chamber and the element acts as the isolation element. The element ensures the effective short-circuit protection of the fuse.

GLD-1/2 fuses uses the thermal and magnetic response principles in order to protect the circuit from over-currents. When an overload or short-circuit occurs, the current through the fuse will rise quickly, generating heat and magnetism. The heat will cause the element to soften, directly affecting the time required for the current to reach the permitted fuse limit. If it surpasses the limit, the element will rupture and the arc will extinguish the current.

GLD-1/2 fuses are designed for medium-voltage applications and are widely used for the protection of secondary circuits. They are suitable for commercial, industrial, and residential applications and can be used in a wide range of electrical systems including distribution systems, motor control centers, and traction power systems. They are incredibly robust and safe, and able to withstand over-currents and short-circuits without compromising the safety of the system.

GLD-1/2 fuses offer a reliable and economical solution for medium-voltage applications. Their elongated design ensures effective arc-extinction, increased current-carrying capabilities, and improved safety. They also feature low power losses and fast response times, making them ideal for protection against dangerous conditions.
