Phoenix Contact Surge Protector, 40kA, 3.7kV, DIN Rail Mount

The Phoenix Contact Solar line string combiner boxes (SCBs) are used in both small rooftop systems and large ground-mounted systems. The main tasks of the SCBs are the surge protection of the PV system, collecting strings (if necessary), and looping through the protective equipotential bonding conductor for the local equipotential bonding.
