Function Of Time Delay Micro Fuses

1. Under normal circumstances, disposable fuse plays the role of connecting the circuit in the circuit.

2. Under abnormal (overload) circumstances, one-time fuse as a safety protection element in the circuit, through its own fuse safety cut off and protect the circuit.

Working Principle Of Time Lag Micro Fuses

When a one-time fuse is energized, the heat converted by electrical energy raises the melt temperature. When the normal working current or allowed overload current passes through, the heat generated will radiate to the surrounding environment through the melt and outer shell, and the heat emitted by convection and conduction will gradually reach the balance with the heat generated.If the heat generated is greater than the heat emitted, the excess heat will gradually accumulate in the melt, causing the melt temperature to rise.When the temperature reaches and exceeds the melting point of the melt, it will make the melt melt, fuse and cut off the current, played the role of safety protection circuit.
