Frequently Asked Questions

What is the BUSSMANN FWP-400A semiconductor fuse used for?

The BUSSMANN FWP-400A is a fast-acting bolt-on fuse used to protect power semiconductors such as diodes, thyristors, and IGBTs in AC/DC circuits. It is commonly applied in variable frequency drives, UPS systems, and industrial power supplies where rapid overcurrent interruption is critical to prevent component damage.

What are the specifications of the BUSSMANN FWP-400A fuse?

The BUSSMANN FWP-400A is a 400 A fast-acting bolt-on fuse from the FWP Series. It has a voltage rating of 700 V AC and 700 V DC, making it suitable for both AC and DC applications. The manufacturer part number is FWP-400A, and it is designed for semiconductor protection.

Where to buy the BUSSMANN FWP-400A fuse worldwide?

You can source the BUSSMANN FWP-400A fuse through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide competitive pricing and reliable sourcing for BUSSMANN products.

How to select the correct BUSSMANN FWP series fuse for an application?

To select the correct BUSSMANN FWP series fuse, match the continuous current rating (e.g., 400 A) to the load current and ensure the voltage rating (700 V AC/DC) exceeds the circuit voltage. Consider the fuse's fast-acting characteristic for semiconductor protection. Always consult the manufacturer's data sheet for I²t and breaking capacity requirements.
