DC Combiner Box 1000 V with Type 1+2 SPD for 1 String and 1 MPPT
The DC combiner box is installed on the DC side of the photovoltaic system, along the line connecting the module string to the inverter input. This compact version is fitted with a combined Type 1+2 surge arrester, to be used when the building is protected by a lightning protection system (LPS) or when there is a risk of a direct lightning strike on the photovoltaic generator or on the incoming lines.
The installed device is a Phoenix Contact Type 1+2 surge protective device for photovoltaics, rated for 1000 V DC and wired for one string on one MPPT input. A combined device of this kind can discharge both lightning current (10/350 µs waveform) and induced surges (8/20 µs waveform), providing coarse protection and fine protection in a single unit. The string connections are made with original Stäubli MC4 connectors.
Key features
Type 1+2 surge arresterThe combined Phoenix Contact surge protective device protects against both lightning current (10/350 µs) and induced surges (8/20 µs).
For buildings with lightning protectionThis is the configuration to choose where an LPS is present or when the photovoltaic array is exposed to the risk of a direct lightning strike.
Up to 1000 V DCRated for the string voltages of photovoltaic systems with 1000 V direct current inverters.
Compact formatAt only 128 mm wide, it also fits into lofts and technical compartments with limited space.
Original Stäubli MC4 connectorsThe string connections use original connectors, compatible with standard photovoltaic cabling.
Weatherproof IP65 - IK08 enclosureHalogen-free recyclable plastic enclosure, resistant to UV rays and impact, suitable for outdoor mounting.
