BK/GMT-3/4A fuse is a type of special type fuse used in many different electrical applications. This type of fuse is one of the most common fuses used and is available in many different shapes and sizes. It is typically used in applications where a high level of protection is needed for circuits and equipment.

The main benefit of BK/GMT-3/4A fuses is that they provide a high level of protection. This type of fuse has a unique design featuring a glass tube that protects the internal components from electrical arc flash. The design also eliminates the need for a grounding cable or ground line that is normally needed by other types of fuses. This makes it easier to install and maintain.

BK/GMT-3/4A fuses come in a variety of amperage ratings, ranging from 1 to 40 amps. These amperage ratings enable them to be used in a wide range of applications, including fuses for motor control circuits, power supply circuits, lighting systems, and even domestic wiring. The amperage rating determines how much current the fuse can handle before it trips and interrupts the current flow.

BK/GMT-3/4A fuses are designed to protect both the downstream equipment and the upstream wiring from accidental over current situations that may occur during normal operation. They have a relatively low melting point and can trip quickly when overloaded or subjected to a short circuit. For this reason, they are used in applications that require a high degree of protection such as circuit breakers and circuit protectors.

The working principle of a BK/GMT-3/4A fuse is relatively simple. When an over current situation occurs the fuse wire inside the glass tube melts, interrupting the circuit and protecting the downstream equipment and wiring from further damage. The fuse has a two-part design, consisting of a metal strip and an insulated glass tube. The metal strip acts as a conductor, carrying the current from the power source to the equipment the fuse is protecting, while the glass tube acts as an insulator, preventing the metal strip from arcing into the equipment. If an over current situation occurs, the fuse melts at a predetermined temperature, interrupting the current and protecting the circuit.

BK/GMT-3/4A fuses are widely used in many different types of applications due to their high level of protection and low melting point. They are used in motor control circuits, power supplies, lighting systems, as well as a range of other applications. They provide a reliable and cost-effective solution for protecting circuits and equipment from over current situations. The wide range of amperage ratings means that there is a BK/GMT-3/4A fuse suitable for all types of applications, making them a popular choice for many electrical installations.
