Select the fuse-link current according to the PV module maximum series fuse rating, expected string current, conductor capacity and complete overcurrent-protection design. The available current range does not mean that a higher fuse rating provides better protection; the selected rating must match the electrical characteristics of the protected photovoltaic circuit.

Overview
Product Overview
UH-DG-FU03 is a 1500V DC gPV fuse-link series designed for photovoltaic string and array overcurrent protection. The 10 × 65 mm platform covers selected ratings from 1A to 35A, including low-current versions for specialized PV circuits and higher-current versions up to 35A for modern solar string protection requirements.
The cylindrical cartridge format is designed for compatible 10 × 65 mm photovoltaic fuse holders, including the UHCCY 35A fuse-holder platform. A common mechanical size across all current ratings allows the required fuse amperage to be selected without changing the corresponding holder platform.

gPV Fuse Classification
The gPV operating category is intended for photovoltaic fuse-link applications requiring protection across the operating and fault-current range of PV strings and arrays.
Standard 10 × 65 mm Format
All current versions use the same compact 10 × 65 mm cylindrical fuse format for compatibility with correctly rated PV fuse holders.
Replaceable Cartridge Design
The cylindrical fuse link can be replaced independently of the fuse holder after the DC circuit has been safely isolated.
Wide PV Selection Range
Low-, medium- and higher-current options allow one fuse platform to serve different module technologies, string layouts and photovoltaic protection requirements.
