Fuseholders

03420828H is a type of fuseholder that’s widely used in various applications. It is a self-supporting, two-piece assembly that is used to mount an inline fuse. This fuseholder consists of a molded plastic base with four mounting holes, and a captive nut assembly that firmly grasps the fuse securely. The 03420828H fuseholder is designed for 0.25 inch x 1.25 inch (6.35mm x 31.75mm)inline fuses for a variety of uses.

Application Field

The 03420828H fuseholder is designed for a wide range of applications, ranging from automobiles and forklifts to appliance and industrial panels. It offers excellent protection and reliability in wind powered and solar power systems. It has a 40 amp rating, which is suitable for low-voltage applications. It can also be used for heavy-duty wiring and is a perfect fit for fusing components in automotive wiring. This fuseholder is ideal for a variety of circuit protection needs, including appliance control, lighting, power distribution, signal and AC power circuits.

Working Principle

The 03420828H fuseholder works on the principle of thermal protection. It works to protect the circuit by opening the circuit when the current is too high. This is accomplished through the use of a thermal element, which is a strip of metal that melts when exposed to excessive current. When the temperature of the metal exceeds the rating of the fuseholder, it melts and opens the circuit, thus providing protection against any further damage due to excess heat or current.

The fuseholder also works on the principle of short circuit protection. In the event of a short circuit, the fuse holder will signal the circuit breaker, which will then trip the switch. This helps to protect the circuit from overloading or short circuiting.

Conclusion

The 03420828H fuseholder is a widely used type of fuseholder, designed for a variety of applications. It offers excellent protection and reliability, with a 40amp rating suitable for low-voltage applications. Its thermal protection mechanism allows it to open the circuits when the current is too high, and its short circuit protection is a great way to protect circuits from overloading or short-circuiting.
