Product Profile

EDS1 Series isolator Parallel wiring, larger aperture, much easier wiring. Suitable for distribution box module with lock installation. Arc extinction time less than 3ms.Modular design. 2 poles & 4poles optional. Comply with IEC60947-3(ed.3.2):2015, DC-PV1standard.

EDS1 series isolation switch is suitable for a power system with rated voltage DC 1200V or below and rated current 32A or below. The product can be used for infrequent switching-on and switching-off and can disconnect 1 – 2 MPPT lines at the same time. It is especially suitable for isolating lines in HVDC transmission and distribution systems, such as cutting off the high voltage DC current between solar panels and inverters.

  • For installation between solar panel and solar charge controller, between solar panel and inverter, between solar panel and solar panel.
  • Pre-wired DC isolators with connectors for faster and safer installation.
  • Load disconnect up to 8 times rated current, ideal for any electrical isolation requirement such as repair, maintenance, inspection, installation, etc.
  • This solar disconnect switch provides an integrated disconnect switch in a self-contained closed form, padlocked to make it locked in the OFF position and tamper-proof.
  • Protect your PV DC disconnect switch from rain, dust and other weather elements
