Fuses

Fuses are one of the most important components of electrical systems, protecting them from damage due to faults or excessive current draw. The 0034.7316 fuse is a type of thermally activated fuse used to protect equipment from over-current, and designed for use in extreme conditions. It is especially popular for use in hard-to-reach areas, since it does not require any external resetting.

Application Field and Working Principle

The 0034.7316 fuse is designed for use in overcurrent protection applications, such as electric motors, power supplies, UPS systems, switchgear and electric relay systems.It works by utilizing a thermal element to detect excess current and open the circuit before the current flow causes any damage.

The thermal element of the 0034.7316 fuse consists of two components: a bimetallic strip and a resistor. The bimetallic strip is composed of two metals with different thermal expansion coefficients, such as steel and copper. When a fault or overcurrent occurs, the current passes through the bimetallic strip and causes it to bend. This movement of the bimetallic strip causes the fuse to open the circuit and interrupts the flow of current.

The resistor is designed to limit the amount of current the fuse can carry without activating the bimetallic strip. This resistor is also used to limit the amount of current that can flow through the fuse in the event of an overload. The total time that the fuse takes to open the circuit when a fault or overload occurs is determined by the length of its time-lag element.

The 0034.7316 fuse is often rated in either amperes or kiloamperes (kA) and is available in a variety of sizes and voltages. It is also temperature-rated, meaning that it can be used in a wide temperature range without having to worry about aging or other thermal effects. Additionally, since the 0034.7316 is a thermally activated fuse, it is resistant to shocks, vibrations and mechanical shocks.

The 0034.7316 fuse is a reliable and durable electrical component that can be used to protect electrical installations from overcurrent or short-circuiting. Its unique design makes it especially suited for use in hard-to-reach areas or extreme conditions, while still offering reliable overcurrent protection.
