Eaton’s New Bussmann Series NH Size Fuses Provide the Industry’s Highest Current Density and Consistent Bolt-Hole Pattern

Power management company Eaton today introduced its new Bussmann series 1000 volts direct current (Vdc) NH size photovoltaic (PV) solar fuses specifically designed for protecting and isolating array combiners, re-combiners, disconnects and inverters. With the industry’s highest current density and two available mounting options, the NH PV fuses provide design flexibility in a compact size.

Eaton’s NH PV fuses meet global agency standards, simplifying designs for worldwide markets, and are available in traditional blade and bolt-on versions. The traditional blade version can be used with a fuse block to provide quick, tool-less replacement for easy maintenance. The bolt-on version can be bolted directly to a bus bar, reducing components and assembly time. With a common bolt pattern, the NH PV fuses are designed to easily integrate into a standardized bus bar design, regardless of fuse ampacity.

“Eaton delivers a range of overcurrent protection devices for solar applications that protect valuable balance of system equipment and support uptime,” said Kevin Calzada, product manager, solar fuses, Eaton’s Bussmann Division. “Our latest NH fuses for PV applications maintain Eaton’s industry-leading efficiency and low-operating temperatures.”
Both fuse versions come with system monitoring accessories that provide dual visual indication and optional microswitches (for traditional blade version only) to make it easier to monitor system processes.
