System solution for photovoltaic systems with connection terminals and entry set? Error-resistant Y circuit with 3 varistors for use according to VDE 0100-712? Low DC protection level: < 4.0?kV (Voc max = 1,000 V DC with V20-C/0-500PV)? 5 parallel connection terminals to 6?mm2 per polarity (+ and -)? V-Tec entries set included? Arrestor, connectable with thermodynamic cut-off unit and visual function display? Encapsulated, non-extinguishing zinc oxide varistor arrestor for use in distributor housings? Polycarbonate housing, weatherproof for outdoor use.Note: 5 PV strings can be switched in parallel on the terminals. The technical data (string voltage, etc.) and the conditions of the converter (number of MPP trackers) must be taken into account.Additional measures may be necessary if there is the risk of condensation formation.
