When a fuse blows, the internal alloy pieces also melt due to overload or malfunction, forming a physical gap in the circuit. This interruption immediately prevents current from flowing into the circuit, preventing electrical damage or potential fire. The main reason for fuse melting is the sudden loss of current in the affected equipment or area.
What happens inside the fuse
1. Overload: Due to inserting too many devices into the same socket or short circuiting, excessive current flows through the circuit and equipment
2. Heating: Excess current heats up the thin metal wires of the fuse. The current increases significantly, and the internal melt heats up and disconnects
3. Melting: The current reaches the melting point and melts.
4. Circuit disconnection: This melting creates a gap in the circuit, effectively “disconnecting the fuse.
5. Current interruption: As the circuit is cut off, the current can no longer reach the appliances or light bulbs connected to it.
