BUSSMANN FWA-150B High Speed Fuse, 150 A, Blade End x Blade End

Bussmann FWA-150B fuse is used in circuits with high current and voltage demands, such as industrial machinery, power distribution units and renewable energy systems, to safeguard components from overcurrent events.

Working Mechanism:

• Bussmann FWA-150B fuse operates based on the principle of current overload protection. Inside the fuse, an element made of a material with a low melting point is housed.
• When the current passing through the circuit exceeds a certain threshold, the conductor heats up due to increased resistance.
• This rise in temperature causes the conductor to melt, creating an open circuit and interrupting the flow of current. This action effectively prevents excessive current from damaging downstream components.

Frequently Asked Questions:

Q. How to select the right fuse for my application's requirements?

A. Proper selection involves considering factors like current, voltage, breaking capacity and the specific application's needs.

Q. Can multiple fuses be used in parallel for higher current applications?

A. Yes, multiple fuses can be used in parallel to achieve higher current ratings.
