Frequently Asked Questions:

Q. What is the difference between a circuit breaker and a fuse?

A. A circuit breaker has an internal switch that trips when there is excess current, whereas a fuse is a metal piece that melts when excess current overloads the circuit.

Q. What is the breaking capacity of Bussmann FWC-20A10F semiconductor fuse?

A. The breaking capacity of the fuse is 50kA at its rated voltage.

Q. What is the difference between interrupting rating and the ampere rating?

A. The interrupting rating is the maximum amount of energy that the device can safely withstand. The ampere rating of a fuse is the amount of current that the fuse will allow to pass before it begins to operate.
