Specialty Fuses

The TPH-80 series AC micro-fuse is a high speed, ultra-fast and flexible explosion-proof micro-fuse. It has a wide range of power supply and can be used for a variety of different applications. This article looks at the applications field and working principle of the TPH-80 series micro-fuse.

Application Field

The TPH-80 series AC micro-fuse is suitable for all applications that require an ultra-fast and flexible explosion-proof micro-fuse. These include communications, medical, aerospace, automotive, metering and more. In addition to that, it can also be used in low voltage DC applications, such as battery protection. This fuse can be offered with breaking capacity up to 108A at 500V AC.

Working Principle

The TPH-80 series AC micro-fuse works by combining a fast-acting ceramic element with an envelope made from PTFE. The element is arranged so that when an over-current occurs, the element will heat up and open the air gap in the envelope. This will break the circuit and cut off the current flow. The TPH-80 series fuse also has a unique thermal feedback system which helps stabilize the temperature of the element and provide long life cycle performance.

Advantages

The TPH-80 series AC micro-fuse offers various advantages, such as its small size, high performance, wide current range, and lightning resistance. In addition, the fuse operation is reliable and it can withstand worksite vibration. This fuse also has excellent thermal stability and can maintain its reliability in the long run, even under extreme temperature ranges.

Conclusion

The TPH-80 series AC micro-fuse is suitable for many different applications that require an ultra-fast and flexible explosion-proof fuse. These include communications, medical, aerospace, automotive, metering, and more. In addition, the fuse offers a wide range of advantages, such as its small size, high performance, wide current range, and lightning resistance. All these features make this a reliable and durable fuse.
