DEHNcombo YPV SCI - now available

DEHNcombo YPV SCI type 1 and 2 combined arrester with SCI technology for PV systems – now available!

DEHNcomboThe DEHNcombo YPV SCI combined arrester from the globally active lightning and surge protection specialist DEHN reliably protects PV systems from surges caused by lightning. For the first time, this new arrester concept combines a number of benefits for PV systems in a single device. The surge protective device combines a type 1 lightning current arrester with a type 2 surge arrester. It incorporates the proven Y circuit with the patented SCI technology and takes up little space. DEHNcombo is tailored to meet the requirements of the new prTS 50539-12 standard, which will be published in autumn 2013, and the national supplement 5 of the DIN EN 62305-3 standard, which will be available in the first quarter 2014.

DEHNcombo YPV SCI is a compact, lightning current carrying combined arrester for the d.c. side of photovoltaic systems which can be used without backup fuse up to 1000 A. It has a total discharge current of 12.5 kA (10/350 μs) and a low voltage protection level, thus allowing coordination with terminal equipment.

The SCI technology with a combined disconnection and short-circuiting device is the core of DEHNcombo. In case of overload, the arrester is safely disconnected and the d.c. switching arc is extinguished since this arrester does not feature a mere disconnector, but a switching concept specifically developed for PV systems.

The devices are tailored to meet the requirements of the new CLC/FprTS 50539-12 standard and the national supplement 5 of the DIN EN 62305-3 standard, which will be available in the first quarter 2014. They have a short-circuit current rating Iscpv of 1000 A d.c. and can thus be used in both small-sized and large-scale systems. DEHNcombo YPV SCI is available for voltages of 600 V, 1000 V and
1500 V.

With a width of only 4 modules, the device is compact and space-saving. Nevertheless, it feature an operating-current-free operating state and fault indication as well as a remote signalling contact which immediately provides information on the availability of each protective circuit.
