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-PV1/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

Product Benefits

  • Installed at any angle can achieve IP67 waterproof level
  • UV resistance and V0 flame retardant material
  • Contact Silver Plating, silver layer thickness to the industry’s highest standards
  • Arcing Time in 3ms
  • Breather valve attached on the bottom of the isolator
  • No Polarity
  • Lockable at OFF position
  • AS 60947.3:2018 and IEC 60947.1:2015 standard
  • 5 years warranty, product insurance, and recall insurance available
