GD-14PV 50A Fuse Link Overview
The GD-14PV 50A fuse link is designed for reliable overcurrent and short-circuit protection in photovoltaic DC systems. With a 50A rated current, 1000V DC voltage rating and compact 14x51mm cylindrical format, this fuse is suitable for solar combiner boxes, inverter input circuits, DC distribution panels and other photovoltaic protection equipment.
The GD-14PV 50A fuse link uses a gPV operating class, which is specifically intended for photovoltaic circuit protection. When correctly selected and coordinated with the PV system, it helps protect cables, conductors and connected equipment from abnormal current conditions.
Its cylindrical ceramic body and metal end caps provide a compact structure that is convenient for installation and replacement. Clear markings on the fuse body allow installers to identify the current rating, voltage, fuse class and applicable standard quickly during maintenance.
The GD-14PV series covers current ratings from approximately 15A to 50A, making it easier for panel builders and solar equipment manufacturers to choose the appropriate fuse according to different PV string currents. The GD-14PV 50A fuse link is the higher-current option within this series.
Product Features
50A Rated Current
The GD-14PV 50A fuse link is rated at 50A and is suitable for higher-current photovoltaic circuits where smaller fuse ratings are insufficient.
1000V DC Protection
Designed for 1000V DC systems, this 1000V DC fuse link can be used in residential, commercial and industrial photovoltaic installations.
14x51mm Cylindrical Design
The standard 14x51mm PV fuse format provides a compact solution for modular DC protection systems while supporting higher current capacity than many smaller cylindrical fuse formats.
gPV Fuse Class
The gPV classification makes the fuse suitable for photovoltaic applications where protection against DC overload and short-circuit faults is required.
20kA Breaking Capacity
The GD-14PV 50A fuse link provides a breaking capacity of 20kA, supporting reliable interruption of DC fault current within the specified operating conditions.
IEC 60269-6 Standard
The GD-14PV series references IEC 60269-6 and UL 248-19, standards associated with photovoltaic fuse protection.

Applications of the GD-14PV 50A Fuse Link
The GD-14PV 50A fuse link is suitable for photovoltaic protection applications including:
- Solar PV combiner boxes
- Photovoltaic string circuits
- DC distribution cabinets
- Solar inverter input protection
- Commercial rooftop PV systems
- Industrial solar installations
- OEM photovoltaic equipment
- Renewable-energy control panels
Its combination of a 50A rating, 1000V DC capability and 14x51mm format makes it suitable for installations that require compact protection with relatively high current capacity.
Selecting a GD-14PV 50A Fuse Link
Before selecting a GD-14PV 50A fuse link, engineers should confirm the PV string current, system voltage, conductor capacity, prospective fault current and equipment requirements.
The fuse rating should not be selected only according to normal operating current. PV module specifications, inverter requirements and protection coordination should also be considered.
For applications requiring lower current ratings, other GD-14PV series options are available between approximately 15A and 50A.
Compatible Fuse Base
The GD-14PV 50A fuse link uses a 14x51mm cylindrical format and can be paired with the GA&DA GDPV-50B DC fuse base.
The combination of:
GD-14PV Fuse Link + GDPV-50B Fuse Base
provides a practical modular protection solution for PV combiner boxes and DC distribution panels. A correctly matched fuse base helps ensure proper installation, reliable electrical contact and convenient replacement.
