The 170M6468 is a high-performance fuse specially designed for current control applications. The fuse is engineered with a higher fire rating compared to general purpose fuses, making it suitable for high-current and low-voltage applications. The fuse also features a short timer delay and patented safety features to provide increased protection against short-circuits, arcing, and other electrical dangers.The main purpose of a fuse is to provide an additional layer of protection against electrical hazards, ensuring the safety of all personnel and equipment connected to the electrical system. By correctly applying the right fuse type to the application, it is possible to prevent damage from short circuits, overloads, and arcing. Fuses also protect surrounding components from damage that could be caused by electrical overloads or surges.

The 170M6468 is a Class H fusing device, certified by UL 4248-1 and UL 4248-2 as well as CSA C22.2 No. 47. This fuse type is suitable for high-current motor loads, such as three-phase motors, as well as low-voltage power feeders. The fuse can also be used in overload protection settings, such as motor starters and other electrical control systems.

The fuse is composed of a ceramic insert, which contains silver-oxide contacts, and a fiber body for strength and insulation. The fibrous body ensures that the fuse does not break or arc during operation. The 170M6468 operates based on the current flowing through the insert. As the current rises above the rated current, the silver-oxide contacts inside the insert start to heat up and expand, eventually causing the contacts to touch and disrupt the current flow. This action triggers an electrical arc that quickly breaks the circuit.

As the 170M6468 is engineered for high current applications, it is generally rated for a breaking capacity of 35kA at 690VAC, with an interrupt rating of 75kA at 277VAC. The fuse operates under a maximum temperature of 450°C and a maximum time delay of 3.3ms. The rated blowing current for this type of fuse is 8.3-125A.

The 170M6468 fuse is an ideal product for three-phase motor loads often found in industrial automation systems, as well as a range of other industrial and commercial applications. With its high breaking capacity and fast response time, the 170M6468 fuse is a reliable component for a wide variety of high-current applications.
