Suntree AC Surge Protector (SPD) 40kA 2 Pole Single Phase Technical Specifications<\/div>\n

<\/p>\n

    \n
  • Device Type:<\/strong> Type 2 AC Surge Protective Device<\/span><\/li>\n
  • Number of Poles:<\/strong> 2 Pole (typically protecting Live and Neutral lines)<\/span><\/li>\n
  • System Phase:<\/strong> Single-Phase<\/span><\/li>\n

    Suntree AC Surge Protector (SPD) 40kA 2 Pole Single Phase Key Features<\/div>\n

    <\/p>\n

      \n
    • Modular Pluggable Core:<\/strong> The device relies on a two-body design. If a massive electrical surge degrades the protective module, you can pull it out and snap in a replacement module without needing to rewire the entire base or power down the whole consumer unit.<\/span>\u00a0<\/li>\n
    • Visual Status Indicators:<\/strong> Features mechanical color-coded flag windows on the front face of each module. Green<\/strong> indicates the device is operating properly; Red<\/strong> indicates the internal thermal\/overcurrent tripping has triggered and the module must be replaced immediately.<\/span>\u00a0<\/li>\n
    • Flame Retardant Design:<\/strong> Constructed using high-grade thermoplastic materials (PBT\/PA66) that comply with UL94 V-0 anti-flaming industrial standards.<\/span>\u00a0<\/li>\n

      <\/ul>\n

      <\/div>\n
      Important Installation Context<\/div>\n

      <\/p>\n

        \n
      • Earthing Requirement:<\/strong> A surge protector cannot function without a dedicated grounding wire. The excess electrical charge requires a short, thick grounding pathway to the earth bar to effectively clear surges.<\/span>\u00a0<\/li>\n
      • Upstream Protection:<\/strong> It must always be installed in parallel with your system and placed downstream of a dedicated backup overcurrent device\u2014such as a 16A to 32A miniature circuit breaker (MCB) or fuse\u2014to prevent continuous fault currents in the event of an SPD failure.<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
