Direct current SPDs are a voltage limiting SPDs providing a single mode of protection, typically installed in DC Distribution Boards (DB)

Main Features: 

• Impulse test classification for 230, 600 and 1000 V DC: Test Class I and II according to IEC 61643-11 and Type 1 and Type 2 according to EN 61643–11. 
• Impulse test classification for 60 and 110 V DC: Test Class II according to IEC 61643-11 and Type 2 according to EN 61643–11.
• Backup protection is not required up to a prospective DC short circuit current of 1000 A (for UN up to 230 V); 
• Three colour Status Indicator with progressive indication of remaining performance. 
• Pollution Degree 3 up to Un 230 V DC. 
• This voltage limiting SPD for photovoltaic systems providing three modes of protection, typically installed close to the PV inverter, close to the PV generator and/or in the junction box, with the following features and benefits: 
  • Impulse test classification: Test Class I and II according to IEC 61643-31 Ed.1 and Type 1 and Type 2 according to EN 61643-31 
  • High short circuit current rating without backup protection Iscpv up to 1000A (according to IEC 61643-31). 
  • High short circuit current rating without backup protection, additionally tested based on IEC/EN 61643-11. 
  • Three colour Status Indicator with progressive indication of remaining performance.
