Electrical, Specialty Fuses

The 004303122 is a specialty fuse, and is part of a wide selection of products in the electrical safety protection and control field. Specialty fuses serve a far more specific purpose than the everyday general steel-shelled cartridge and strip fuses; they are designed for particular specialty roles as directed by their codes.

004303122 Application Field

The 004303122 specialty fuse is created with two main circuit protection and control requirements in mind: to protect electrical devices and equipment against overload, and to protect against short-circuits.

The 004303122 specialty fuse has long been used to protect motors, control systems, UPSs, power supplies, marine equipment, medical equipment, and commercial and industrial equipment. This particular fuse specializes in continuous fault clearing, and is able to circuit short-circuit current ratings up to 8 kA.

004303122 Working Principle

The fuse element of the 004303122 specialty fuse is designed to melt down when current flow exceeds the predetermined rating. This is done by a section of the fuse with a lower melting point that melts down and triggers an arc. At this point the fuse opens and stays open, thereby breaking the electric circuit.

The arc is rapidly extinguished thanks to the arc-quenching material in the fuse. The opposite end of the fuse will then respond by securely resetting the electric circuit. This rapid resetting ensures that the short-circuit or overload will not cause a permanent damage, and that normal operation can continue as soon as possible.

004303122 Characteristics

The 004303122 has a rated voltage of 690V and a rated current of 32A. Its breaking capacity is 3200A, and it’s able to operate in temperatures ranging from -25°C to + 85°C (-13°F to -185°F).

The fuse measures 58mm x 21.6mm x 10mm, with an operating life of 1,500 operations. It also comes with a series of external control systems that are able to monitor, detect, and control the system’s operations.

Conclusion

The 004303122 specialty fuse is an efficient and reliable solution for protecting electrical devices and equipment against overload and short-circuits. These fuses are able to quickly clear faults and reset electric circuits, and are capable of operating in a wide range of temperatures. This allows them to be used in a variety of applications, written on a case-by-case basis.
