The 170M3439 is a specialty fuse from Eaton’s Bussmann division and is designed to provide an extra level of protection for high-end components. It is commonly used in industrial equipment, communications systems, computers, and audio/visual equipment. The fuse is UL/CSA listed. It has a voltage rating of 250VDC and rapid-acting, time-delay characteristics for protection of sensitive electronic circuitry.

The fuse consists of a cylindrical, metal-encased fuse element, housed inside an insulating epoxy enclosure. It is designed to be extremely robust and provide protection against shock, vibration, and extreme temperatures. The fuse element is constructed by a tubular wire core filled with a non-combustible granular or powder-like filler material. This filler is composed of a combination of metals such as zinc, copper, gallium, tin, and manganese. The filler material is pressed and swaged into the core, affording the fuse with superior mechanical strength and abrasion resistance.

The fuse element is then placed in a male/female threaded casing, with the cut-off part facing the closed end of the case. The casing is then filled with molten polymer which seals the fuse element and ensures its safety and long life. The casing is then fitted with appropriate terminals and pressure-fit markers.

The fuse works on the principle of an over-current or short circuit. It is designed to protect sensitive components from damage due to over-current or short-circuiting. When the electrical current flowing through the circuit exceeds the safe amperage rating of the fuse, the fuse element melts due to the excess heat produced, breaking the circuit and preventing further damage. Once the fault condition is eliminated, the fuse element cools and can be replaced and the circuit can then function as usual.

The 170M3439 fuse is designed for use in many industries including industrial, computer, and telecommunications applications. It has a wide temperature range, an interrupt rating of 35A, and a current rating of 10A. It is a highly reliable and safe choice for protecting sensitive circuitry from damage due to over-current or short-circuiting.
