Frequently Asked Questions
What is the Phoenix Contact Surge Protection Box?
The surge protection box (String Combiner Box) is a DC connection box for photovoltaic systems. It combines up to 8 string inputs to 4 MPP trackers and protects the DC side with combined surge protection type 1 and type 2 up to 1000 V input voltage. The set is supplied as two enclosures, each measuring 180 x 508 x 111 mm.
Which systems is the box suitable for?
The box is suitable for PV systems with up to 8 strings and 4 MPP trackers. Up to 20 A per string and up to 40 A per MPPT are permissible, with a maximum DC input voltage of 1000 V (open-circuit voltage up to 1100 V). Connection is made via spring or screw terminals for cross-sections of 4–6 mm².
Are string fuses included?
No, string fuses are not included and must be added separately if required. There is also no integrated string monitoring – the box focuses on combining the strings and DC surge protection type 1 and type 2.
Is the box suitable for outdoor use?
Yes. The enclosure complies with protection class IP65, making it dust-tight and protected against jet water. Operation is possible at ambient temperatures down to -20 °C, so the box can also be used outdoors and in winter operation.
