Details

Three-step d.c. switching device (patented SCI principle)
The DEHNcombo YPV SCI ... combined arrester protects equipment in photovoltaic systems against lightning currents.

Thanks to its application-optimised discharge capacity of 6.25 kA (10/350 µs) per pole, DEHNcombo is tailored to meet the requirements of the latest version of the EN 50539-12 standard and Supplement 5 of the German DIN EN 62305-3 standard.
With a short-circuit current rating of 1000 A, DEHNcombo easily meets all requirements placed on surge arresters in small, medium and large photovoltaic systems and can be used without additional backup fuse in all photovoltaic systems up to 1000 A.
Due to its enclosure design which is specifically adapted to the system-specific requirements, even the version for voltages up to 1500 V can be used without taking special precautions (e.g. safety distances). The combined arrester has a width of only four modules, thus allowing space-saving installation.

The patented three-step d.c. switching device (SCI principle) provides an extremely high degree of safety which is required in modern photovoltaic systems. DEHNcombo YPV SCI is available for voltages of 600 V, 1000 V and 1500 V, covering the most common voltage levels of photovoltaic systems.
The fault-resistant Y circuit and the combined disconnection and short-circuiting device further reduce the probability of an arrester failure in case of the operating and fault states which have to be considered in photovoltaic systems. This ensures reliable operation of the PV system at any time.

A low own consumption of the devices is also an important aspect in PV systems. The operating state / fault indication, which needs no power to operate and instantly provides information on the operating state of the arrester, also fulfils this requirement. With its optional floating changeover contact, the remote signal can be used as a break or make contact according to the particular circuit concept.
