Product Description

The BUSSMANN FWH Series Semiconductor Fuse (MPN FWH-325A) is a fast-acting bolt-on fuse rated at 325 A, 500 V AC, and 500 V DC. This AC/DC voltage type fuse is designed for semiconductor protection applications.

Frequently Asked Questions

What is the BUSSMANN FWH-325A semiconductor fuse used for?

The BUSSMANN FWH-325A is a fast-acting bolt-on fuse designed to protect power semiconductors such as diodes, thyristors, and IGBTs from overcurrent faults. It is commonly used in industrial drives, power supplies, and UPS systems where rapid clearing of high fault currents is critical to prevent component damage.

What are the specifications of the BUSSMANN FWH-325A fuse?

The BUSSMANN FWH-325A is part of the FWH Series, rated at 325 A with a voltage rating of 500 V AC and 500 V DC. It is a fast-acting, bolt-on type fuse designed for semiconductor protection. The manufacturer part number is FWH-325A.

Where to buy the BUSSMANN FWH-325A fuse worldwide?

You can source the BUSSMANN FWH-325A 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 on this fast-acting semiconductor fuse.

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

To select the correct BUSSMANN FWH series fuse, match the continuous current rating (325 A for FWH-325A) to the load, ensure the voltage rating (500 V AC/DC) exceeds the system voltage, and verify the fast-acting characteristic suits the semiconductor's surge withstand. Always consult the manufacturer's data sheet for I²t and clearing time curves.
