SPP-4F200

SPP-4F200 series of electrical specialty fuses are a widely used form of current protection in various applications. They are used as a source of power to protect equipment and circuits from overcurrent or short circuit conditions. The SPP-4F200 series provides a reliable, cost-effective solution to protecting sensitive or hazardous areas.

Type

The SPP-4F200 series is a time delayed dual element fuse which features an exceptionally fast operating time of 10 microseconds. It is available in both dual-stack and single-stack configurations and is available with a variety of ratings including 2.5A to 20A. There are also several types of trip time ratings offered, such as type SPP-4F200-5, which has a trip time rating of 5 seconds.

Features and Benefits

The SPP-4F200 series provides a variety of benefits and features, including its fast trip time, relatively low external thermal resistance, low-cost construction, and its wide range of fuse ratings. The fuse is also designed to be easy to install and is easy to reset, making it simple to protect equipment from overcurrent or short circuit conditions.

Working Principle

The operating principle of the SPP-4F200 involves the interaction of two elements: a fuse element and an arc suppressor. When the current passes through the fuse element, it begins to heat up until it reaches a temperature where it melts, thus breaking the circuit. The arc suppressor then intercepts any current surge from the melted fuse element and dissipates it harmlessly. This dual element design means that the fuse is more capable of preventing damage from an unexpected current surge.

Application Field

SPP-4F200 series of fuses can be used in a variety of applications. They are ideal for applications where high currents are expected but need to be kept below a certain level in order to avoid potential damage. They are commonly used in military and industrial applications such as aircraft or vehicles, as well as in residential and commercial settings, particularly in outdoor circuits that require protection from surges.

Conclusion

The SPP-4F200 series of fuses from are a reliable, cost-effective solution to protecting sensitive or hazardous areas. The fast trip time, relatively low external thermal resistance, low-cost construction, and wide range of fuse ratings make it an ideal choice for a variety of applications. The dual element design means that the fuse is more capable of preventing damage from an unexpected current surge, making it an excellent choice for applications where high currents might be expected.
