PRODUCT INFORMATION

Mersen DC Surge Protection Device – DC Power Line Protection

The ISP2-40K1000V-PV series is a line of devices providing enhanced overvoltage protection for photovoltaic systems by utilizing a thermally optimized disconnect system by Mersen, which eliminates the need for additional overcurrent protection (backup fuses) due to its high short-circuit withstand rating. These surge protection devices are suitable for all PV applications: large-scale DC installations, rooftop, and off-grid systems. The series includes specific multi-pole devices for multiple MPPT (Maximum Power Point Tracking) inverters.

FEATURES

  • Maximum discharge current (8/20μs): 40 kA
  • Rated discharge current (8/20μs): 10 kA, 20 kA
  • Ucpv: 65, 80, 660, 1060 Vdc and 1000 Vdc
  • Ispv: 10 kA (EN50539-11), no backup fuse required
  • SCCR: 50 kA, 65 kA, 100 kA (UL 1449 4th ED.)
  • Can be DIN-rail mounted, plug-in format
  • Specific products for multiple MPPT with UL 1449 certification
  • Reversible frame allowing cable entry from top or bottom
  • Mechanically encoded cartridge to prevent cartridge replacement errors
