BUSSMANN FWC-20A10F High Speed Fuse, 20 A, 500 V

Bussmann FWC-20A10F semiconductor fuse is designed to safeguard sensitive components and devices from overcurrent conditions, short circuits and excessive power surges. It is ideally used in electronics, automotive and industrial systems.

Working Mechanism:

• When the current passing through the fuse exceeds its 20A rating or encounters a short circuit, the fuse responds swiftly. Its semiconductor construction rapidly interrupts the excessive current flow, preventing damage to sensitive components and equipment.

Features:

• Bussmann FWC-20A10F semiconductor fuse features compact construction for ensuring minimum power loss and low energy let-through.
• It can be operated at voltages up to 600VAC and 700VDC.
• This semiconductor fuse has interrupting capacity of 200kAIC at 600VAC and 50kAIC at 700VDC.
• It has amperage ratings up to 20A and has ferrule end connections that provide an enclosed connection to reduce the risk of accidental contact with live parts.

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.
