What is a Surge Protective Device (SPD)?
A Surge Protective Device (SPD) is an essential electrical component designed to protect electrical equipment from damage caused by sudden voltage spikes, known as surges. These surges can result from
• Usage: Low Voltage, Solar PV
• Safety Standards: IEC•Type: Thermal DC fuse
• Certification:TVU、CE、IEC
• Short-circuit breaking capacity 33KA
• 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
