5SD7 Surge Arresters Type 2

• Protects low-voltage systems against transient overvoltages
• For installation downstream of lightning arresters 5SD7, type 1 in main distribution boards or subdistribution boards
• Remote signaling contact notifies whether a protection module has been disconnected from the grid by the thermal isolating arrester or whether a protection module is not plugged in
• Note: It is essential to have standardized protection against lightning and voltage spikes to ensure error-free operation of photovoltaic systems!

 

5SD7 Surge Arresters type 1,2 and3

• Universal application in all main distribution cabinets due to compact design (47 mm)
• Easy and quick installation on the 40 mm busbar with safety interlocking and protection against mismating
• Cost and time savings in an additional supply upstream from the meter such as the modem or gateway
• Three-pole remote signaling contact (-R) for monitoring the device function remotely
• Compliance with requirements of the DIN VDE 0100-443 and -534 standards as well as DIN VDE AR-N 4100

5SD7 lightning arresters

• Protects low-voltage systems against overvoltage and high currents triggered by direct or indirect lightning strikes
• Enclosed lightning arresters suitable for installation upstream of the meter
• All design variants fitted with remote signaling contact
• Suitable for installation in main distribution boards, upstream or downstream of the meter

5SD7 combination arrester

• Compact designs that can be used as both lightning arrester (type 1) as well as surge arrester (type 2)
• Protects low-voltage systems against overvoltage triggered by lightning strikes or grid switching operations
• Thermal isolating arrester disconnector offers a high level of protection against overload

5SD7 combiantion surge arresters

• Protects low-voltage systems against overvoltage and high currents triggered by direct lightning strikes
• Thermal isolating arrester disconnector offers a high level of protection against overload
• All design variants fitted with remote signaling contact
• Suitable for installation in main distribution boards downstream of the meter
