3.15A 5x20mm Delay Ceramic Fuse

The ceramic fuse works by breaking the circuit when the rated current passes through it. When the current flowing through the fuse exceeds the rated current, the thin wire melts and breaks the circuit. It protects circuit elements against breakdowns caused by overcurrent.

The difference of delayed fuses is that they do not react immediately and do not cut the circuit immediately when the current value they can withstand is exceeded. This ensures that the circuits are not interrupted, especially when using products that draw high current at first, such as motors.
