Product description

Product description

System solution for photovoltaic inverter with 2 separate MPP trackers


• Varistor arrester, connectable with disconnecting device in error-resistant Y circuit to VDE 0100-712 (50539-12)

• Low DC protection level: < 4.0 kV (Uoc max = 1,000 V DC with V20-C/0-500PV)

• Low DC protection level: < 3.0 kV (Uoc max = 900 V DC with V25-B+C/0-450PV)

• Per protection device, there are 4 terminals up to 6 mm² pre-mounted in the housing, up to 30 A DC per terminal

• Pre-mounted in polycarbonate housing (IP66), UV-resistant for the use outside, including cable gland kit



For DC protection of the inverter in photovoltaic systems.

If there is a danger of condensation forming through wind, ice, temperature or sunlight, further measures may be necessary!
