170M5438

170M5438 Electrical Specialty Fuses are an essential component of any electrical system, providing protection against potentially dangerous electric current surges. These surge protectors differ from normal electrical fuses in that they offer high level, non-time-dependent protection against erratic or sustained high current. This type of fuse also provides protection against short-term overloads and surges.

These types of fuses are specifically designed to limit current when presented with a given over-current condition. Generally, the fuse is designed to offer several levels of protection against increasing current values. This allows the fuse to remain serviceable in the event of a trip-free condition or even some very specific, known current loads. For example, a surge protector may offer protection against up to twenty times its rated current, as well as against current surges of up to several hundred amperes.

The operation of the fuse follows standard electrical principles. When the fuse is subject to an over-current condition, a metal strip housed in a glass-encapsulated body melts, releasing a semi-conductive gas or material into the circuit. This gas quickly terminates the flow of current, thus preventing further damage due to the over-current. Because of this rapid current cut-off, the fuse is able to react to a high current surge in a fraction of a second.

The 170M5438 Electrical Specialty Fuses are designed for use in high temperature applications. Certance rated these electrical fuses for use with AC loads of up to 7200V/ 70A and DC loads of up to 7200V/ 50A. This product also features an UL, CSA and IEC ratings of 600V. These fuses have a glass/ceramic body and special temperature compensating elements for improved operating safety and performance.

The 170M5438 Electrical Specialty Fuses also provide an expiration indicator. This indicator appears in the form of a red line on the label of the fuses, which is visible when the fuse has been in use for too long or has been operated for longer than the stated time limit. As such, these fuses help to ensure that system operators are aware of the age and condition of the fuse and make it easier to identify any potential problems.

The 170M5438 Electrical Specialty Fuses offer an efficient and cost-effective way to protect against uncontrolled surges, overloads and short circuits. Their fast-acting nature and high level of protection further enhance their value in ensuring the safety of circuits and components. Coupled with their expiration indicator, the 170M5438 Electrical Specialty Fuses are an ideal choice for any application requiring reliable surge protection.
