*4pole 2string* Kraus and Naimer DC Isolator - KG20-4
DC isolator which is highly versatile and suits nearly all domestic PV installations. We usually supply the model with a black handle so that it is visually different from the AC isolators - but red/yellow versions are available if you prefer.
The handle can be padlocked in the off position, meaning that if work needs to be done to the inverter, the DC supply can be safely and securely isolated.
This listing is for a two string (2x2 pole) isolator. (This is the version without links - see also the 2pole 1string)
Suitable for most domestic PV systems.
