products description

The influence of current

The upper limit of ambient air temperature shall not exceed 90 ℃; The lower limit of ambient air temperature shall not be lower than -50 ℃; The altitude of the installation location shall not exceed

Over 2000m (if you want to exceed this 2000m, please specify the requirements, and our company can design and develop according to customer requirements).

The influence of voltage

The rated voltage of photovoltaic fuses does not need to be reduced for installation at an altitude not exceeding 5000m, but it is subject to air pressure

The impact has a certain influence on the power frequency withstand voltage and insulation performance. The test voltage for DC 1001-1500V is 3820V

Our products should reach at least 6000V, so there is no need to consider it here.

Usage category

GPV "refers to a DC fuse with full range breaking capacity used for overcurrent protection in solar photovoltaic systems.

Structural characteristics

The variable cross-section melt made of silver sheet is encapsulated in a high-strength melt tube, which is filled with chemically treated high

Pure quartz sand and specially treated chemical materials are used as arc extinguishing media, and the two ends of the melt are firmly connected to the contacts through spot welding.
