UH-DG-FH02 uses a 10 × 85 mm gPV fuse link. Select the fuse-link current rating according to the PV module maximum series fuse rating, expected string current, conductor capacity and complete 1500V DC protection design. The holder's 32A rating defines the holder limit and does not determine the required fuse amperage.

Overview
Product Overview
UH-DG-FH02 is a single-pole 1500V DC fuse holder designed for 10 × 85 mm photovoltaic fuse links. With a 32A holder rating and 35 mm DIN-rail mounting, it provides a modular fuse interface for PV string protection inside combiner boxes, DC distribution panels and related solar protection equipment.
The removable fuse carrier allows the 10 × 85 mm fuse link to be accessed independently of the permanently mounted base, simplifying fuse replacement after the DC circuit has been safely isolated. The ventilated housing is designed for high-voltage photovoltaic protection applications where compact DIN-rail installation is required.

1500V DC PV Platform
UH-DG-FH02 is designed as a 1500V DC fuse-holder platform for high-voltage photovoltaic string and array protection applications.
10 × 85 mm Fuse Format
The holder accommodates 10 × 85 mm cylindrical photovoltaic fuse links, a common format for 1500V DC PV string protection.
32A Holder Rating
The fuse holder is rated at 32A. The current rating of the installed fuse link is selected separately according to the photovoltaic circuit protection design.
Removable Fuse Carrier
The fuse link is installed in a removable carrier, allowing the fuse to be replaced while the DIN-rail base remains installed inside the enclosure.
35 mm DIN-Rail Mounting
The single-pole housing mounts on a standard 35 mm DIN rail for integration into PV combiner boxes and DC distribution equipment.
Ventilated Housing
Multiple ventilation openings are integrated into the housing to support heat dissipation around the fuse chamber during normal operation.

Installation
Installation Guidance
1. Fully isolate the photovoltaic DC circuit before installing or servicing the UH-DG-FH02 fuse holder.
2. Mount the fuse holder securely on a standard 35 mm DIN rail inside the electrical enclosure.
3. Select a 10 × 85 mm gPV fuse link with voltage and current ratings suitable for the 1500V DC photovoltaic circuit.
4. Insert the fuse link completely into the removable fuse carrier and confirm that both fuse ferrules are correctly seated in the carrier contacts.
5. Insert and close the fuse carrier completely before energizing the circuit.
6. Connect the DC conductors according to the photovoltaic circuit design and verify polarity before commissioning.
7. Check the DIN-rail mounting, terminal connections, fuse seating and carrier closure before energizing the circuit.
8. Never remove the fuse carrier or replace the fuse link while the DC circuit is under electrical load. Isolate the circuit before servicing.
