Fuseholders are devices that secure and protect a fuse from overheating, voltage fluctuations, and other electrical issues. The BK/1A3399-04 is a type of fuseholder specifically designed to hold one fuse. It is mainly used in telecom applications.

Overview of the BK/1A3399-04 Fuseholder

The BK/1A3399-04 is a snap-in fuseholder designed to accommodate both standard and high inrush fuses with a maximum current rating of 10 A. It is RoHS compliant and its operating temperature range is from 0 °C to +125 °C. It has a horizontally or vertically mounted aluminum finned heat sink and is enclosed in a UL 94-V0 rated PBT housing material. Additionally, the fuseholder is rated IP20, has a panel fixing surface, and measures a depth of 33mm.

Application Fields of the BK/1A3399-04

The primary application field of the BK/1A3399-04 fuseholder is telecom applications. It can be used in telecom systems, such as power supplies, routers, base station cabinets, PDUs, and GSM/LTE base stations. Additionally, the fuseholder can also be used in other applications, such as industrial and residential switchgears, automotive circuits, motor power circuits, railway signaling power supplies.

Working Principle of the BK/1A3399-04

The BK/1A3399-04 is designed to operate in two modes. The first mode is the normal operating state, during which the fuse will draw a maximum of 10 A current. The second mode is the over-current/short circuit state, when the fuse will automatically act as a switch to protect the circuit from short circuit to a certain limit. The working principle of the BK/1A3399-04 is to provide reliable overcurrent protection for telecom systems, without having to manually change the fuse or turn off the circuit. If there is an overload, the fuse will disconnect the circuit and protect it from short circuits, increasing the safety and reliability of the circuit.

Conclusion

The BK/1A3399-04 fuseholder is a reliable device designed to provide over-current protection in telecom systems. It is rated IP20, with a maximum current rating of 10 A and an operating temperature range from 0°C to +125°C. The fuseholder is mainly used in telecom applications such as power supplies, routers, base station cabinets, PDUs, and GSM/LTE base stations. Additionally, it can also be used in other applications, such as industrial, residential, automotive, and railway signaling power supplies.
