Superior Protection for Solar Power Applications

New Cooper Bussmann® PV Fuse Protects Photovoltaic Systems up to 1000Vdc

The demand for alternative energy has led to another innovation from Cooper Bussmann, the industry leader in circuit protection. Developing sophisticated solar panel systems have accelerated the demand for high performance fuses. The short-circuit conditions associated with solar panels do not allow for sufficient current to open a standard fuse in a way that effectively isolates faulted photovoltaic (PV) strings. The new Cooper Bussmann® PV Fuse line provides a full range of protection that traditional fuses cannot.

Low Level Fault Protection
• PV Fuses are full range fuses and can clear faults as low as 1.3 x I(fuse rating) @ 1000Vdc. They are designed specifically for thin film cell and 4˝, 5˝ and 6˝ crystalline silicon cell based panels.

Superior Cycling Withstand
• PV Fuses are tested to withstand cycling conditions associated with solar panel system operation and environmental influences.

1000Vdc Capacity
• PV Fuses are designed with a maximum 1000Vdc operating voltage based on typical solar panel systems with L/R of 1ms and below.

Globally Accepted 10x38mm Dimension
• All PV Fuse amp ratings are available with standard ferrule, bolt and versatile PCB mount options.

Class of Operation: gPV and UL PV fuse links

Description:
A range of fuse links in a 10x38mm package specifically designed for the protection and isolation of photovoltaic strings. The fuse links are capable of interrupting low overcurrents associated with faulted PV (reverse current, multi-array fault) string arrays.

Fuse Size: 10x38mm

PV Fuses are specifically designed to work in solar panel systems using 4”, 5” and 6” cells.
