Ferraz Shawmut is now - Mersen

Founded in 1969, Norberg~IES is a leading distributor for Mersen (formerly Ferraz Shawmut which was formerly Gould Fuses) fuses from high speed DC to high voltage fuses. Mersen also offers an extensive offering of fuse blocks, clips, and power distribution blocks and fusible and non-fusible disconnect switches. We maintain an extensive on-site inventory of factory-direct fuses and accessories that carry a manufacturer-backed warranty. This differentiates us from other internet sources that provide surplus or re-conditioned fuses, both that can introduce potentially harmful risk in an electrical circuit. To read more about surplus fuses click on this link from the National Electrical Manufacturers Association referencing water damage and electrical equipment. A picture of a failed high voltage fuse, resulting from exposure to water is also shown. Many surplus fuses have been exposed to water from sitting outside unprotected after being discarded by the original user. In addition to carrying standard and specialty products from Mersen, Norberg~IES can build UL listed fusible and non-fusible disconnect switches in our 30,000 square foot facility located in the heartland of America, Tulsa, OK. Protecting Your People, Your Equipment What is circuit protection really? More than a safeguard for your power supply, it's how you protect your two most valuable assets: your people and your equipment. At Ferraz Shawmut, this understanding is at the heart of everything.
