SURGYS® G51-PV

Surge arrester – Type 2

for photovoltaic installations

SURGYS G51-PV - 1000 PV
SURGYS G51 – 1000 PV
Function
  • SURGYS G51-PV surge Protective Device is designed to ensure protection for photovoltaic supply networks against transient overvoltages. It is compliant with test requirements UTE 61-740-51 and EN 50-539-11 as well as with installation requirements UTE C 15-712-1.
Advantages
Monobloc base with plug-in module
  • The SURGYS is supplied complete and ready for installation. Its Monobloc base is fitted with replaceable plug-in modules which, at the end of their service life, can be easily and quickly replaced without having to disconnect the Monobloc base.
Remote signalling
  • The remote plug-in signalling contact allows alarm report to a supervision station.
New 1500 VDC version
  • Adapted to the protection of high power installations.
Applications
Main incoming protection in a photovoltaic network:

  • SURGYS G51-PV is installed on the DC side, in the combiner box, close to the solar cell strings, forprotecting the downstream DC equipment from the indirect effects of lightning.
  • SURGYS AC, SURGYS D40 for instance, is installed downstream of the inverter for load protection.
