Overview
Product Overview
UH-PC-MF01 is a 1000V DC inline fuse solar connector designed to integrate photovoltaic string protection directly into the DC cable connection. The housing accommodates a standard 10 × 38 mm cylindrical PV fuse link, allowing the fuse rating to be selected according to the protection requirements of the photovoltaic circuit.
Unlike the standard UH-PC-MC01 Solar Connector, UH-PC-MF01 incorporates an inline fuse holder within the connector assembly. It uses an Ø4 mm contact system and PC insulated housing with IP67 protection when correctly assembled and mated. Tin-plated copper contacts are standard, with silver-plated copper contacts available on request.

Applications
Where This Product Is Used
Solar PV Systems
Protection, connectivity and distribution components for photovoltaic arrays, string circuits and related solar DC systems.
UH-PC-MF01 is intended for photovoltaic strings that require localized DC overcurrent protection in the cable connection. Typical uses include PV module strings, extension wiring and array circuits where reverse-current or parallel-string fault protection is required by the system design.
Installation
Installation Guidance
1. Determine the required photovoltaic fuse rating from the PV module, string configuration and complete circuit protection design.
2. Use a 10 × 38 mm PV fuse link with voltage and current ratings suitable for the circuit.
3. Ensure the photovoltaic circuit is isolated before opening the fuse connector or installing the fuse link.
4. Install the fuse link fully inside the UH-PC-MF01 fuse chamber and close the connector body securely.
5. Check the connector housing, sealing surfaces and fuse-holder assembly before mating.
6. Mate the corresponding connector interfaces completely and confirm that the locking structure is engaged.
7. Verify polarity and complete assembly before the photovoltaic circuit is energized. Never replace the fuse while the circuit is under load.

FAQ
Frequently Asked Questions
What fuse size does UH-PC-MF01 use?
UH-PC-MF01 is designed for a 10 × 38 mm cylindrical photovoltaic fuse link.
What fuse current rating should I install?
Select the fuse rating according to the PV module maximum series fuse rating, string short-circuit current, cable capacity and applicable system protection requirements. UH-PC-MF01 does not require one fixed fuse amperage for every installation.
What is the difference between UH-PC-MF01 and a standard solar connector?
Unlike the UH-PC-MC01 Solar Connector, UH-PC-MF01 incorporates a 10 × 38 mm inline fuse holder so that photovoltaic string overcurrent protection can be integrated directly into the connector assembly.
Should a gPV fuse be used?
A gPV fuse is the standard photovoltaic fuse category used for PV string protection. The selected fuse must also have voltage and current ratings suitable for the specific photovoltaic circuit.
Can the fuse be replaced?
Yes. UH-PC-MF01 is designed around a replaceable 10 × 38 mm fuse link. The photovoltaic circuit must be safely isolated before the fuse holder is opened or the fuse is replaced.
Are silver-plated contacts available?
Yes. Tin-plated copper contacts are supplied as standard, while silver-plated copper contacts are available on request.
