Electrical, Specialty Fuses

004724115 is an electronic fuse designed to protect sensitive electronics and electrical devices from dangerous electrical current and voltage. The specialty of this type of fuse is its dual thermal and magnetic sensing mechanism. The heat generated by the electric current is sensed by a bimetallic strip, and the magnetic field generated is sensed by a magnetically sensitive fluid-filled element. When either one or both of these mechanisms detects a dangerous level of heat or magnetic force, the resulting signal triggers an electronic switch that cuts off the power to the electronic device, preventing any further damage.

In general, there are two different types of 004724115 fuses; one is a slow-blow type fuse and the other is a fast-blow type. The difference lies in the way the fuse operates when exposed to elevated levels of current or voltage. The slow-blow type will initially trigger at a lower current level than the fast-blow type, but will take much longer to reach the breaking or cut-off point.The slow-blow type fuse is most appropriate for applications where the power supply can remain stable but with fluctuating current levels, such as in voltage regulation circuits. The fast-blow type fuse is better suited for applications where extended protection is needed for short arcs or surges of high voltage, such as in motor starting circuits.

This type of fuse is designed to be mounted directly onto a printed circuit board or other PCB, eliminating the need for additional wiring and reducing the risk of accidental contact with live wires. Due to their very small size, they can also be embedded into the PCB itself, providing highly effective and reliable protection.The construction of 004724115 fuses is typically based on one of two technologies: the solid-state or the arc-resistant. The solid-state types use a bimetallic strip as the main triggering element, while the arc-resistant types use the large surface area of an arc chamber and a heated metal rod to absorb excess current.

Overall, 004724115 fuses offer an extremely reliable solution for protecting sensitive electronics and electrical devices from over-voltage or current fluctuations. Their small size and low profile makes them both unobtrusive and easy to install, and their dual thermomagnetic sensing mechanism allows for a wide range of applications. The fact that they are electrically powered, and not dependent on any other source, also allows them to provide superior protection against surges and arcs of dangerous current or voltage.
