Product Description

The BUSSMANN FWP Series Semiconductor Fuse (MPN FWP-90B) is a fast-acting bolt-on fuse rated at 90 A, 700 V AC, and 700 V DC. This non-indicating fuse is designed for AC/DC voltage types and is part of the FWP series.

Frequently Asked Questions

What is the BUSSMANN FWP-90B semiconductor fuse used for?

The BUSSMANN FWP-90B is a fast-acting bolt-on fuse used to protect power semiconductors such as diodes, thyristors, and IGBTs in industrial drives, UPS systems, and power conversion equipment. Its 700 V AC/DC rating makes it suitable for high-voltage DC bus applications.

What are the specifications of the BUSSMANN FWP-90B fuse?

The BUSSMANN FWP-90B is a 90 A, fast-acting, non-indicating semiconductor fuse from the FWP series. It is rated for 700 V AC and 700 V DC, with a bolt-on mounting style. The manufacturer part number is FWP-90B, and it supports AC/DC voltage types.

Where to buy the BUSSMANN FWP-90B fuse worldwide?

You can source the BUSSMANN FWP-90B 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 right BUSSMANN FWP series fuse for my application?

To select the correct BUSSMANN FWP series fuse, match the continuous current rating (e.g., 90 A for the FWP-90B) to your load, and ensure the voltage rating (700 V AC/DC) exceeds your system voltage. Consider the fuse's fast-acting characteristic for semiconductor protection and verify bolt-on dimensions fit your panel.
