Frequently Asked Questions
What is the difference between a relay and a fuse?
A fuse can only open the circuit, while a relay can both open and close the circuit.
What is the difference between fuses and MCBs?
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.
How do these fuses break the circuit?
When an excessive current passes through electrical fuses, the wire inside heats up and breaks, which opens the circuit.
What is the significance of the current rating in a fuse?
The continuous flow of the highest amount of current that a fuse can handle without melting is the current rating of the fuse.
What is the difference between a circuit breaker and a fuse?
A fuse melts when there is too much current, while a circuit breaker trips when there is excessive current or a short circuit.
