170M4447

170M4447 is an electrical specialty fuse manufactured by Bussmann. It is designed to protect differently rated circuits against overload and short circuiting. The fuse is currently available in two ratings: Class K5 and K6, in accordance with UL 581. It is intended to be used in a variety of applications ranging from motor control centers and similar apparatus to factory assembly lines, commercial and residential wiring systems, and many other industrial applications.

The 170M4447 fuse is constructed with a cylindrical body made of a copper alloy. The fuse is filled mainly with sand, which ensures a good thermal transfer between the body and the fuse contacts. The body also features a black casing that encloses the two contacts, as well as a glass section in order to inspect the fuse without having to remove it entirely. The casing also provides extra protection against dust and other contaminants.

The fuse has two distinct types of operating principle. The first type is an overload operation, where the fuse triggers when the current draw exceeds the rated value. This type of reactive response not only protects the circuit from overload, but it also prevents overheating of the components.

The second type of operation is short-circuit protection, whereby the fuse triggers when the current draw is greater than the rated short-circuit current. This helps to protect the circuit from high temperature which can arise when a short circuit occurs.

The 170M4447 fuse is a common fuse used in a wide range of applications, from small motor and appliance applications requiring overload protection to heavier industrial applications requiring both protection from overload and short-circuits. The 170M4447 is a great choice for those seeking an economical, reliable solution for protecting circuits from overload and short-circuits.
