The upper limit of ambient air temperature shall not exceed 90°C. The lower limit of ambient air temperature shall not be less than -40°C. The elevation of the installation site should not exceed 2000m (Special requirements for elevations exceeding 2000m can be designed and developed upon request).
Usage Category
"gPy" refers to a DC fuse with full range breaking capacity used for overcurrent protection in solar photovoltaic systems.
Insulating Case
High quality flame-retardant housing. Smooth surface, strong insulation and flame retardant performance.
Replaceable Core
Use with high-quality core matching 10x38 fuse core replacement is more convenient.
Pure Copper Component
It has good electrical conductivity.
Guide Mounting
Easy to install and efficient to use.
The variable cross-section melt made of pure silver sheet is encapsulated in a melt tube made of high-strength porcelain. The melt tube is filled with chemically treated high-purity quartz sand and specially treated chemicals as the arc extinguishing medium. The two ends of the melt are firmly connected with the contact by spot welding.
