40 AMP Bussmann Fusetron FRN-R-40 Time Delay Fuse

The Bussmann Fusetron FRN-R-40 is a time delay fuse designed for overcurrent protection in electrical circuits. This fuse is particularly known for its reliability in industrial and commercial applications, providing a safeguard against overloads and short circuits. Its time-delay feature allows it to withstand brief surges of current, which often occur during motor start-ups, without blowing immediately. This characteristic makes the Fusetron FRN-R-40 especially suitable for use in motor circuits, where a sudden inrush of electricity can cause nuisance tripping of standard fuses. Bussmann, a brand under Eaton Corporation, has a long history of manufacturing high-quality fuses and fuse holders. The FRN series, including the FRN-R-40 model, is widely recognized in the electrical industry for its performance and durability. These fuses are typically utilized in various sectors such as manufacturing, construction, and energy management. The FRN-R-40 provides a balance of responsiveness and endurance, ensuring both protection and continuity of operations in critical electrical systems. Its unique features include a glass tube design that allows for visual inspection of status, as well as a low voltage drop to improve efficiency in power distribution.
