How to reduce DC Isolating Switch failure frequency?
To fundamentally reduce the failure rate of DC isolating switch, you need a three-pronged strategy: selecting arc-resistant, certified components, such as Suntree's specialized models;
• Usage: Low Voltage, Solar PV
• Safety Standards: IEC•Type: Thermal DC fuse
• Certification:TVU、CE、IEC
• Short-circuit breaking capacity 50KA
• Plug Design, quick change fusible core Improve efficiency
• Indicator window design, signal of whether the fused core is fused or not (the light is on when it is blown, it is not on)
• PA66 flame retardant material
• Overload protection and short circuit protection
• Busbar design, reliable and beautiful wiring
• Photovoltaic set of strings all need to be equipped with DC fuse protection circuit to remove faults
