BUSSMANN FWP-35A High Speed Fuse, 35 A, 1400 VAC

Bussmann FWP-35A semiconductor fuse is used in electrical systems to protect sensitive semiconductor devices from overcurrent conditions. It is ideal for power electronics, motor drives and renewable energy systems. This fuse rapidly interrupts the circuit in case of excessive current, preventing damage to semiconductors and ensuring operational safety.

Working Mechanism:

• It operates based on the principle of a fast-acting current interruption mechanism. When the current passing through the fuse exceeds its rated value, due to a short circuit or an overload, the fuse responds rapidly to prevent damage to the connected semiconductor devices.
• The fusible element inside has a low melting point. When a high current flows through the fuse, the heat generated causes the fusible element to melt. This melting creates an open circuit, breaking the electrical connection and stopping the current flow.

Frequently Asked Questions:

Q. What should I do if this BUSSMANN FWP-35A fuse stops due to a problem?

A. Find out the cause of the problem and fix it. Replace the fuse with a new one if required.

Q. How do I replace a blown Bussmann FWP-35A fuse?

A. To replace a blown fuse, ensure that the circuit is de-energized. Then, remove the blown fuse from its holder and replace it with a new fuse of similar specifications.

Q. What is the significance of the current rating in a fuse?

A. The continuous flow of the highest amount of current that a fuse can handle without melting is the current rating of the fuse.
