Ferraz Fuses


Founded in 1969, Norberg~IES is a leading distributor of Ferraz Fuses. Powerfuse.com offers an extensive line of products from high-speed DC and high-voltage fuses, to an offering of fuse blocks, clips, power distribution blocks, and fusible and non-fusible disconnect switches.


Established in 1969 by industrialist Hans Norberg, Norberg-IES has been a recognized source of value-added products for the electrical industry. Norberg~IES is divided into two, easily identifiable brands: Nema7 for enclosures, and Powerfuse.com for high-voltage fuses.
