GDPV-22B DC Fuse Base Overview
The GA&DA GDPV-22B DC fuse base is designed for photovoltaic and other high-voltage DC protection systems that require reliable fuse mounting, easy replacement and compact panel installation. Rated at 50A and suitable for 1000V / 1500V DC applications, this series is built for 22x58mm gPV fuse links and is widely suited for solar combiner boxes, inverter-side protection, DC distribution cabinets and renewable energy equipment.
The GDPV-22B family includes two main versions:
- GDPV-22B – standard version
- GDPV-22BZ – version with status indication
Both versions are available in 1P and 2P configurations, making the series flexible for different photovoltaic system layouts.
This product family combines a practical modular structure with convenient operation during installation and maintenance. The holder is suitable for TH35 DIN rail mounting, helping panel builders integrate fuse protection neatly with other DC devices such as breakers, isolators and surge protective devices.
The larger 22x58mm fuse format allows the GDPV-22B series to support higher-current PV circuits while keeping the design compact enough for modern electrical enclosures. Clear front marking helps users quickly identify the model and operating voltage during panel assembly, inspection and replacement work.
