GDPV-50 DC Fuse Base Overview
The GA&DA GDPV-50 DC fuse base is designed for photovoltaic and other high-voltage DC protection systems that require reliable fuse mounting, convenient maintenance and compact panel installation. With a rated current of 50A and support for 1000V / 1500V DC applications, the series is suitable for modern solar combiner boxes, DC distribution panels, inverter input circuits and renewable-energy control equipment.
The GDPV-50 family currently includes three 1P versions:
- GDPV-50D
- GDPV-50L
- GDPV-50LZ
These models share the same basic application direction but use different mechanical structures to meet different installation and maintenance requirements.
The GDPV-50L and GDPV-50LZ are designed for 10x85mm and 14x85mm cylindrical PV fuse links. GDPV-50L provides a standard fuse-holder configuration, while GDPV-50LZ adds a status indication function for easier inspection.
The GDPV-50D uses a different front-operating enclosure design. Its slim structure is suitable for installations where panel space, operating access and component arrangement are important.
All versions are intended for gPV photovoltaic fuse applications and can be integrated into modular DIN rail assemblies together with DC circuit breakers, surge protective devices and other PV protection components.
For solar equipment manufacturers, panel builders and distributors, the GDPV-50 series provides several mechanical options within one product family, helping simplify selection for different project and cabinet designs.
Product Features
50A Rated Current
The GDPV-50 series supports a rated current of 50A, making it suitable for photovoltaic circuits that require higher current capacity than common 32A fuse-holder systems.
This allows the series to be used in larger PV strings, DC distribution equipment and other renewable-energy applications where increased current capability is required.
1000V / 1500V DC Capability
The series supports both 1000V and 1500V DC systems.
The 1500V DC capability is particularly useful in modern photovoltaic installations where higher string voltages are used to reduce current losses and improve system design efficiency.
gPV Photovoltaic Protection
GDPV-50 fuse bases are intended for gPV fuse applications. When used with an appropriately selected photovoltaic fuse link, the holder forms part of a protection system designed to isolate overcurrent and short-circuit faults in PV circuits.
Multiple Product Designs
The GDPV-50 family includes different mechanical configurations rather than relying on one housing design for every application.
This gives panel builders greater flexibility when considering:
- panel depth
- available DIN rail space
- operating access
- fuse replacement method
- visual inspection requirements
The different versions can therefore be selected according to actual installation conditions instead of only electrical ratings.
10x85mm / 14x85mm Fuse Compatibility
GDPV-50L and GDPV-50LZ support 10x85mm and 14x85mm cylindrical PV fuse links.
Supporting two fuse formats makes the series more flexible for OEM manufacturers and distributors handling different photovoltaic fuse specifications.
Optional Status Indication
The GDPV-50LZ version includes status indication, providing an easier way to check fuse condition during routine maintenance.
In installations containing many protected PV strings, visual indication can help technicians identify the relevant circuit faster and reduce troubleshooting time.
DIN Rail Installation
The modular structure is suitable for DIN rail mounting, allowing the fuse base to be installed alongside other DC protection devices.
This helps maintain a clean panel layout and simplifies equipment assembly, replacement and future system expansion.

Applications
The GDPV-50 series is suitable for photovoltaic and high-voltage DC systems where dependable fuse installation and convenient maintenance are required.
Typical applications include:
- Solar PV combiner boxes
- Photovoltaic string protection
- DC distribution panels
- Solar inverter input circuits
- Commercial rooftop PV systems
- Utility-scale photovoltaic projects
- Renewable-energy control cabinets
- Industrial DC distribution equipment
- OEM solar protection assemblies
- Battery-related DC systems
The combination of 50A current capacity and up to 1500V DC capability makes the GDPV-50 suitable for both conventional photovoltaic installations and newer high-voltage solar systems.
For panel manufacturers, its modular structure helps organize protective devices within limited cabinet space. For maintenance teams, the replaceable fuse design allows an operated fuse link to be serviced without replacing the entire fuse base.
