Solarmi DS50PVS-500/G surge arrester, 500Vdc, CE

Xtend Solarmi DS50PVS-500/G

The DS50PVS/G series surge arresters are surge arresters specially developed for protecting photovoltaic installations against surges and are available in versions for voltages of 500/800/1000 V DC. The exchangeable modules allow easy replacement of a damaged part without the need to dismantle the connected wires.

Surge arresters contain a high-performance varistor and a gas-filled spark gap in a so-called Y connection. This special combination enables error-free insulation resistance measurement, as no leakage current occurs.

DS50PVS/G series arresters are supplied as standard in a version with remote fault signaling.

Features:

• 
  
• Surge protection for photovoltaics type 2
  
• Leakage current per pole: In = 20 kA / Imax = 40 kA
  
• Safe disconnection device
  
• No aging due to leakage currents
  
• Fault-tolerant Y-connection
  
• Insulation resistance measurement is not subject to error
  
• No damage occurs in the event of insulation failure
  
• Modular structure
  
• Remote signaling contact as standard
  
• Complies with EN 61643-11 and IEC 61643-1 standards
