The Suntree Solar PV DC Fuse Link with Holder 1P 1000Vdc<\/span>\u00a0is a specialized electrical safety device engineered specifically for overcurrent and short-circuit protection in photovoltaic (PV) systems, battery banks, and combiner boxes<\/mark>.\u00a0<\/div>\n
By containing both the fast-acting fuse link and the safe-disconnect holder in a single-pole unit, it isolates faulty solar strings to prevent thermal runaway, fire risks, and catastrophic equipment damage.\u00a0<\/div>\n

    \n
  • Rated Operating Voltage (\\(U_{e}\\)):<\/strong> 1000V DC \/ 1100V DC<\/strong><\/span><\/li>\n
  • Number of Poles:<\/strong> 1P (Single Pole)<\/strong><\/span><\/li>\n
  • Standard Ampere Options:<\/strong> Typically available from 1A up to 30A \/ 32A<\/strong> for the standard compact housing (commonly stocked in 15A, 20A, 25A, and 32A variants).<\/span><\/li>\n
  • Fuse Cylinder Dimensions:<\/strong> Standardized 10×38 mm<\/strong> cylindrical gPV fuse link.<\/span><\/li>\n
  • Rated Breaking Capacity:<\/strong> 30 kA<\/strong> at 1000Vdc, delivering high-level short-circuit limitation.<\/span><\/li>\n
  • Mounting Standard:<\/strong> 35mm DIN rail compatible<\/strong> for modular integration into distribution boards or combiner boxes.<\/span><\/li>\n
  • Material & Safety:<\/strong> Enclosed in a 960\u00b0C flame-retardant, V0-class thermoplastic<\/strong> housing with an IP20 ingress protection rating.<\/span>\u00a0<\/li>\n

    Suntree Solar PV DC Fuse Link with Holder 1P 1000Vdc Key Operational Features<\/div>\n

    <\/p>\n

      \n
    • Fast-Acting gPV Performance:<\/strong> The internal pure silver melt element features a rapid 1\u20133ms time constant<\/strong>, breaking abnormal currents swiftly before they can flow back into sensitive solar panel strings.<\/span><\/li>\n
    • Safe Disconnect under Maintenance:<\/strong> The holder acts as a pull-out fuse-disconnector, allowing technicians to completely isolate an individual circuit line safely. Note: The carrier text explicitly warns: Do not open under load<\/strong>. Always turn off the DC isolator or circuit breaker before pulling the fuse.<\/em><\/span>\u00a0<\/li>\n
    • Robust Environmental Durability:<\/strong> Designed to operate efficiently across extreme temperatures ranging from -40\u00b0C to +85\u00b0C<\/strong> and built to withstand prolonged corrosive\/acidic environments.<\/span>\u00a0<\/li>\n

      Suntree Solar PV DC Fuse Link with Holder 1P 1000Vdc Correct Sizing Rule of Thumb<\/div>\n
      <\/div>\n

      <\/p>\n

      When installing these fuses on your PV inputs, the rated current of the fuse link should be sized to 1.25 to 1.5 times<\/strong> the short-circuit current (\\(I_{sc}\\)) of your solar panel string. This buffer prevents nuisance blowing from minor daytime spikes while maintaining sharp protection against actual fault currents<\/div>\n
