GD-13PV 25A Fuse Link Overview
The GA&DA GD-13PV 25A fuse link is designed for photovoltaic DC systems requiring reliable overcurrent and short-circuit protection at high operating voltages. With a 25A rated current, 1500V DC rating and 14x85mm cylindrical format, it is suitable for solar string circuits, combiner boxes, DC distribution equipment and inverter-side protection.
The GD-13PV series is specifically intended for gPV photovoltaic protection. This operating class is designed for PV circuits where current behavior and fault conditions differ from conventional AC systems.
The 25A model uses a compact cylindrical construction with metal end contacts and a clearly marked ceramic body. Product identification, current rating, voltage and standard information can be easily checked during installation or replacement.
The GD-13PV family covers a wider current range from 8A to 50A, allowing system designers to select a suitable fuse rating according to string current and equipment requirements. The 25A version provides a practical option for many medium-current photovoltaic applications.
For complete fuse protection assemblies, GD-13PV fuse links can be matched with compatible GDPV-50L / GDPV-50LZ and GDPV-50D series fuse bases.
Product Features
1500V DC High-Voltage Capability
The GD-13PV is rated for 1500V DC, making it suitable for modern high-voltage photovoltaic installations.
Higher DC system voltages are widely used in commercial and utility PV projects because they can reduce current levels and improve overall system design efficiency.
25A Rated Current
This model has a rated current of 25A. It should be selected according to the actual PV string current, conductor capacity and protection coordination requirements.
14x85mm Cylindrical Format
The fuse uses a 14x85mm cylindrical format, providing a compact protection solution while supporting the higher voltage requirements of photovoltaic systems.
The standardized format also makes replacement and stock management easier for installers, distributors and maintenance teams.
gPV Operating Class
The gPV classification identifies the fuse as a photovoltaic protection device.
It is intended to interrupt abnormal currents in PV circuits and protect conductors and associated equipment when correctly coordinated with the electrical system.
20kA Breaking Capacity
The GD-13PV series provides a 20kA breaking capacity, allowing the fuse to interrupt significant DC fault currents within its specified operating conditions.
IEC 60269-6 Compliance
The series is designed according to IEC 60269-6, the international standard covering fuse-links for photovoltaic systems. Product documentation also references UL 248-19.

Applications
The GD-13PV 25A fuse link is suitable for photovoltaic systems where high DC voltage and dependable circuit protection are required.
Typical applications include:
- Solar PV string protection
- Photovoltaic combiner boxes
- DC distribution cabinets
- Solar inverter input circuits
- Commercial rooftop PV systems
- Utility-scale solar installations
- Renewable-energy control panels
- OEM photovoltaic equipment
- High-voltage DC protection assemblies
Its 1500V DC capability makes the GD-13PV especially suitable for newer photovoltaic installations designed around higher string voltages.
Product Selection
Correct fuse selection should consider more than the rated current alone.
Before choosing the 25A model, engineers should verify:
- Maximum PV string current
- System DC voltage
- Cable and conductor capacity
- Fuse operating class
- Prospective fault current
- Compatible fuse holder
- Upstream and downstream protection
- Module and inverter requirements
The GD-13PV series provides multiple current ratings between 8A and 50A, so the correct rating can be selected according to actual circuit requirements rather than using one fuse specification for every PV string.
Compatible Fuse Base
The GD-13PV series can be used with compatible GA&DA photovoltaic fuse bases including:
- GDPV-50L
- GDPV-50LZ
- GDPV-50D
Using a matched fuse link and fuse holder helps ensure correct physical installation and provides a coordinated protection solution for photovoltaic DC circuits.
This also allows distributors and panel builders to source both protection components from the same product range.
