SS-5H-1A-BK

Introduction

A fuse, in its simplest form, is an electrical device consisting of a thick wire that melts easily when too much current passes. The uniform melting point and the consistent current rating of the wire ensures proper protection for the electrical system. Among the various types of fuses available on the marker, SS-5H-1A-BK is a type of 5 x 20mm fuse.

Application Field

The SS-5H-1A-BK fuse can be used as an over-current protection device in acoustic equipment, telecommunications products, power supply, display systems, consumer electronic products, instruments, lights, electron tools, medical equipment and other components of the circuit.

Working Principle

The fuse consists of an element, which was a fine wire made of metal alloy in its protect, housed in a ceramic or plastic body. This wire is a low resistance conductor, it melts and separates the circuit when current surge is detected. The fuse has two important parameters: rated current and rated voltage. When the current exceeds its rated value, it will melt quickly and the load will disconnect immediately. As the time-current characteristic curve of the fuse clearly shows, the melting time is inversely proportional to the value of the current.

The SS-5H-1A-BK fuse has a current rating of 1A and a voltage rating of 250V. It has various applications such as over-current protection of the circuit, electronic current overload protection, and it is also used to protect transformers. It is also suitable for protecting often-operated relays, motors, and capacitive load.

Advantages of SS-5H-1A-BK Fuse

The SS-5H-1A-BK fuse boasts a number of advantages:

• It has high breaking capacity and high performance.
• It is a low-impedance fuse, so it can respond quickly to an overload.
• It has the ability to withstand high-frequency transients.
• It is also non-ageing, which means it’s not susceptible to deterioration over time.

Disadvantages of SS-5H-1A-BK Fuse

Despite the advantages, the SS-5H-1A-BK fuse also has some disadvantages that should be considered when choosing a fuse:

• It is usually more expensive than other fuses.
• It has a limited voltage rating and current rating.
• It does not offer any indication when it’s been used.

Conclusion

The SS-5H-1A-BK fuse is an ideal choice for over-current protection of the circuit, because of its high breaking capacity, quick response time, and reliability. It is suitable for protecting often-operated relays, motors and capacitive load, while also offering reasonable protection against electrical surges and high frequency transients. However, with its limited voltage and current ratings, and its rather pricey cost, one should consider other options before settling for this fuse.
