Fuses preserve circuits when overloaded. Fuses activate when a fusible, or easily melted, internal wire within the component overheats. The circuit then breaks and shuts off. After that, power cannot completely run through the circuit.
Fuses rely on melting wires. After a fuse burns out, replace it immediately. Fuses generally cost less and offer simplicity compared to a circuit breaker.
Circuit breakers use mechanical operation and require maintenance. When a circuit breaker trips, manually reset the circuit breaker. They do not require replacement parts when tripped. Circuit breakers cost more but offer a more convenient reset.
Both CSA and UL Listed, FTZ Industries fuses come in glass tube or blade styles with various amperages and voltages, such as 125 volt AC and 32 volt DC, to work in a variety of electronic circuit applications:
