A fuse can only open the circuit, while a relay can both open and close the circuit.
A fuse is a metal piece that melts when there is an excess current due to overload, while a circuit breaker has an internal switch that gets tripped when there is excess current in the circuit.
When an excessive current passes through electrical fuses, the wire inside heats up and breaks, which opens the circuit.
The continuous flow of the highest amount of current that a fuse can handle without melting is the current rating of the fuse.
A fuse melts when there is too much current, while a circuit breaker trips when there is excessive current or a short circuit.
