SPP-7H900

SPP-7H900 Application Field and Working Principle

The SPP-7H900 is an ultra-high power application field special and fast-breaking electric fuse, specifically designed for use in high voltage, high frequency power systems. This fuse has been designed using patented induction metering technology to ensure maximum speed and precision in its operation. The SPP-7H900 fuse works with the most efficient, reliable, and quickest method available in the industry today.

Application Field

The SPP-7H900 has fantastic application use, due to its ultra-high power rating. The fuse can be used in almost any application that requires a high voltage and high frequency electrical connection. It is suitable for use in welding and arc welding applications which requires high electrical currents travelling at high speeds. Additionally, the fuse is also recommended for use in medium to high voltage motors and main power lines. The super-high power rating of the SPP-7H900 allows it to be used as an overcurrent protection device for large capacitor banks. All of these solutions require extreme tolerance for short-term faults or volumetric overloads.

Working Principle

The SPP-7H900 fuse works by using induction metering technology which works on the principle of generating a high-speed magnetic flux from the electric current flowing in the fuse, causing an internal diaphragm in a chamber to move in reaction to the generated field. This reaction pushes a plunger, which exerts force on the internal contacts of the fuse. When the force exceeds the resistance of the contacts, it causes a current interruption or short-circuits the circuit. The speed of the reaction is so high that the SPP-7H900 can break short circuit currents in less than 10 milliseconds.

Benefits

The SPP-7H900 provides numerous benefits when compared to traditional fuses. It is far easier to install and replace than traditional fuses, due to its superior design and patented technology. The fuse also has a remarkable thermostability, withstanding up to 20Khz frequency for long periods of time without any degradation in performance. The SPP-7H900 also has an incredibly light weight, making it easier to install in tight spaces. It also has superior shunt current interrupting characteristics, making it suitable for protecting devices such as control circuits and lighting circuits, as well as smaller circuits with low voltage. It is also extremely efficient, as it can break short circuit currents in less than 10 milliseconds, preventing the associated power loss and arc flash.

Conclusion

The SPP-7H900 is a fast-breaking, ultra-high power rated electric fuse that is suitable for use in high voltage, high frequency power systems. It has numerous advantages compared to traditional fuses, including ease of installation, thermostability, light weight, superior shunt current interrupting, and faster current breaking times. The SPP-7H900 is an ideal solution for applications requiring superior current breaking performance and reliability.
