GDPV-50B DC Fuse Base Overview
The GA&DA GDPV-50B DC fuse base is designed for photovoltaic and other DC protection systems that require reliable fuse mounting at higher current levels. Rated at 50A and 1000V DC, it is suitable for 14x51mm cylindrical PV fuse links and can be used in solar combiner boxes, DC distribution panels, inverter input circuits and industrial renewable-energy equipment.
The series includes two main versions:
- GDPV-50B – standard version
- GDPV-50BZ – version with status indication
Both versions are available in 1P and 2P configurations, giving panel builders greater flexibility when designing different DC protection layouts. The 1P model is suitable for single-pole applications, while the 2P version can be selected where two-pole protection is required.
The front-access structure is designed to simplify inspection and fuse replacement. Its modular housing also helps keep electrical panels organized when fuse holders, circuit breakers, surge protection devices and other components must be installed in the same enclosure.
For distributors and OEM manufacturers, the GDPV-50B series provides a practical middle-range option between smaller 10x38mm fuse systems and larger 22x58mm fuse solutions.
Product Features
50A Rated Current
The GDPV-50B supports a rated current of 50A, making it suitable for photovoltaic circuits that require more current capacity than standard 32A fuse-base solutions.
1000V DC Application
A 1000V DC rating makes the series suitable for many modern photovoltaic systems, including string protection, combiner boxes and DC distribution equipment.
14x51mm Fuse Compatibility
The holder is designed for standard 14x51mm cylindrical PV fuse links. This size offers a practical balance between compact installation and higher current capability.
1P and 2P Options
Available pole configurations include:
- 1P
- 2P
These options allow the same product family to be used in different circuit designs without introducing an entirely separate fuse-base series.
Optional Status Indication
The GDPV-50BZ version includes a status indication function. This can make maintenance more efficient in larger solar panels where multiple fuse holders are installed together and quick circuit identification is important.
DIN Rail Installation
The modular housing is suitable for DIN rail installation, supporting clean integration inside combiner boxes and DC cabinets. This installation method also simplifies component replacement and panel expansion.
Practical Front Access
The front-operating structure gives technicians convenient access during inspection and maintenance. Correct circuit isolation should always be completed before opening or replacing a fuse.
