028707.5H Circuit Protection

Fuses: 028707.5H Application Field and Working Principle

Fuses are important safety components, which are designed to protect electrical circuits from damage caused by an overload or short circuit. 028707.5H is a type of fuse and it is widely used in many fields. In this article, we will discuss its application fields and working principle.

Application Field

028707.5H is a class CC type fast-acting fuse. It is suitable for use in circuits with currents up to 30 amperes. It has a rated voltage of 250V and it is rated for use in UL applications. This type of fuse is most commonly used in electronic and electrical equipment such as alarm systems, computer systems, lighting fixtures, transformers, pumps, and other low voltage circuits.

This type of fuse is also used in industrial applications such as power supplies, machine tools, motors, fans, controllers, and other equipment. It is also used in automotive applications like electric cars, recreational vehicles, and boats. It is also used in circuit breakers and other control equipment. The 028707.5H is UL and CSA approved for use in the US and Canada.

Working Principle

The working principle of the 028707.5H fuse is simple. When there is an overload or short circuit in the circuit, the current passing through it will heat up the fuse element, which will expand and eventually break. This breaks the circuit and prevents any further damage or fire hazard.

The 028707.5H fuse is designed so that it operates quickly in the event of a short circuit or overload. It does this by cutting off the current flow before the circuit can reach dangerous levels. This provides protection against damage and it also makes the circuit less susceptible to damage from a current surge.

Conclusion

The 028707.5H is a type of fast-acting class CC type fuse. It is suitable for use in circuits with currents up to 30 amperes, and it is rated for use in UL applications. It is most commonly used in electronic and electrical equipment such as alarm systems, computer systems, lighting fixtures, transformers, pumps, and other low voltage circuits. It is also used in industrial applications such as power supplies, machine tools, motors, fans, controllers, and other equipment. The 028707.5H fuse operates quickly in the event of a short circuit or overload, protecting the circuit from damage.
