Introduction

KLKD.200H is a specialty fuse manufactured and sold by KAI Fong Group Limited. The device has a breaking capacity of 200 amps and can be used in a wide range of applications requiring extra protection. It can be used in any area of the power system that needs extra protection without the need for an auxiliary switching system. The working principle is based on the very simple and reliable principle of overcurrent protection. In essence, when the device senses an overcurrent, it opens the circuit so that the excessive current can no longer flow and damage the system.

Application Field

KLKD.200H specialty fuse is suitable for use in any application that requires overcurrent protection. This includes applications such as motor control, residential and commercial lighting, and other residential and industrial applications. The device can also be used in high-voltage protection circuits where a higher breaking capacity is required. Furthermore, the device can also be used in surge protection circuits – these are circuits designed to protect sensitive electronic equipment from damaging voltage spikes.

Working Principle

KLKD.200H specialty fuse works based on the principle of overcurrent protection. In essence, when the device senses an overcurrent in a particular circuit, it opens the circuit and breaks the connection. This helps to prevent potential damage to the system caused by the excess current. The device works by separating the circuit into two parts – one with high current and the other with low current. The high current is then regulated by the device, and the low current passes through the device to the other end.

Construction and Specifications

KLKD.200H specialty fuse is designed for use in high-voltage protection circuits. It is constructed with a polyester film with thicknesses ranging from 80-120 micrometers. The device has a breaking capacity of 200 amps and a voltage rating of up to 500V AC, making it suitable for high-voltage applications. Furthermore, the device has a rated temperature of up to 80°C, making it suitable for use in many harsh conditions as well.

Advantages

KLKD.200H specialty fuse offers a number of advantages to users. Firstly, the device is designed to provide overcurrent protection without the need for an auxiliary switching system. This helps reduce costs and complexity. Furthermore, the device is also designed to withstand harsh environments, including those with high temperatures. Additionally, the device offers a high-voltage rating of up to 500V AC and is designed to provide reliable operation.

Disadvantages

KLKD.200H does have some disadvantages that users should take into account. Firstly, the device requires a higher-than-normal breaking capacity and can only be used in high-voltage applications. Furthermore, due to the construction of the device, it may be susceptible to corrosion. Additionally, the device has a limited voltage rating, which could be a problem if users require a higher voltage rating.

Conclusion

KLKD.200H specialty fuse is a reliable and high-quality device used for overcurrent protection in many applications. It offers a high breaking capacity of 200 amps and can be used in high-voltage systems. The device is also designed to withstand harsh environmental conditions and is relatively cost effective. However, it is important to take into account its limited voltage rating and the possibility of corrosion.
