UH-DG-FH03 accepts a 10 × 65 mm gPV fuse link. Select the fuse current rating according to the PV module maximum series fuse rating, string operating current, conductor capacity and complete 1500V DC protection design. The holder's 35A rating defines the holder limit and does not mean every installation should use a 35A fuse.

Overview
Product Overview
UH-DG-FH03 is a single-pole 1500V DC fuse holder designed around the 10 × 65 mm photovoltaic fuse format. With a 35A holder rating and DIN-rail mounting, it provides a compact replaceable-fuse interface for PV string protection inside combiner boxes and other DC protection equipment.
The removable fuse carrier allows the gPV fuse link to be accessed independently of the installed base after the DC circuit has been safely isolated. Compared with the longer 10 × 85 mm UHCCY fuse-holder platform, UH-DG-FH03 uses the shorter 10 × 65 mm fuse format while increasing the holder rating to 35A.

1500V DC PV Platform
UH-DG-FH03 is designed for photovoltaic DC protection applications with a fuse-holder rated voltage of 1500V DC.
35A Holder Rating
The holder is rated at 35A, while the installed fuse-link current rating is selected separately according to the protected photovoltaic circuit.
10 × 65 mm Fuse Format
The fuse carrier accepts cylindrical 10 × 65 mm gPV fuse links used for photovoltaic string and array protection.
Removable Fuse Carrier
The fuse is installed inside a pull-out carrier that can be removed from the fixed holder base after the DC circuit has been safely isolated.
DIN-Rail Installation
The modular single-pole housing is designed for DIN-rail installation inside PV combiner boxes and DC protection enclosures.
Ventilated Housing
Ventilation openings are integrated into the housing around the fuse compartment to support thermal management during normal operation.

FAQ
Frequently Asked Questions
What fuse size does UH-DG-FH03 use?
UH-DG-FH03 is designed for 10 × 65 mm cylindrical gPV fuse links.
What is the rated current of UH-DG-FH03?
The fuse holder is rated at 35A. The installed fuse link may have a lower current rating and should be selected according to the photovoltaic circuit protection requirements.
What is the difference between UH-DG-FH02 and UH-DG-FH03?
UH-DG-FH02 – 1500V DC PV Fuse Holder uses the longer 10 × 85 mm fuse format and has a 32A holder rating. UH-DG-FH03 uses a more compact 10 × 65 mm fuse format and is rated at 35A.
What current ratings are available for 10 × 65 mm PV fuses?
1500V DC 10 × 65 mm gPV fuse systems are available in multiple current ratings up to 35A. The actual UHCCY fuse range should be selected from the confirmed UH-DG-FU03 supply configuration.
