DC isolator / switch-disconnector for the DC side of a PV array. The SISO-40 is a 4P unit covering 2 strings, rated to 1200V DC with the poles wired in series. Compliant with IEC/EN 60947-3 and AS 60947.3 — satisfies the mandatory DC switch requirement on PV installations.

No polarity sensitivity — positive and negative terminals are interchangeable. Knife-edge self-cleaning contacts and long arc chambers handle DC breaking duty. Poles can be bridged in series, parallel, or a combination via supplied links to match your voltage and current requirements.

  • 32A Ie at 1000V DC (4-pole series config)
  • 40A Ie at 600V DC (4-pole config)
  • IP66NW enclosure — rated for outdoor mounting
  • Cable range: 4–16mm², rising-clamp M5 terminals, torque to 1.8–2.0Nm
  • Operating temp: –40°C to +85°C (derate above 40°C ambient)
