Fuses

Fuses are an vital element in the electrical safety system of most modern buildings and residential complexes. The 04941.75NR fuse is a high quality, double-pole, single throw fuse that is designed for use in applications of up to 400 Amps. It is designed to protect both the electrical systems and the people using them by providing one or more levels of overcurrent protection. This article will discuss the application field and working principle of the 04941.75NR.

Application Field

The 04941.75NR is intended for residential, commercial, and industrial electrical systems. This type of fuse is used for primary overcurrent protection in the following applications: branch and feeder circuits in industrial, commercial, and residential buildings, motor operations, short-circuit protection, and remotely mounted control panels. It is suitable for use with copper or aluminum conductors, as well as in both AC and DC systems. The 04941.75NR is UL and CSA listed for use in applications up to 400 Amps.

Working Principle

A 04941.75NR fuse consists of two parts: a fusible metal element and a housing. The metal element is encased in an insulating material such as a ceramic or polypropylene tube. When an overload current occurs, the element will begin to melt, causing an open circuit. This prevents further damage to the electrical system by stopping the current from passing through it. The housing, also known as the shell, protects the fuse from being damaged by physical contact or exposure to the environment. The 04941.75NR is designed to open the circuit only when the current exceeds 400 Amps and to survive the short-circuit currents found in normal everyday operation.

Conclusion

The 04941.75NR is an important element in the safety of modern residential, commercial, and industrial electrical systems. It is a double-pole, single throw fuse that is designed for use in applications of up to 400 Amps. It provides two levels of overcurrent protection and is UL and CSA listed for use with copper, aluminum, AC, and DC systems. The 04941.75NR is invaluable for protecting both the electrical system and the people using it from dangerous currents.
