STP T1+2 5 PV is the PHOTOVOLTAIC range of combined Type 1+2/Class I+II devices intended for discharging lightning currents (10/350 ?s) and protecting against induced voltage surges (8/20 ?s), in accordance with EN 50539-11 and IEC 61643-31 standards. These products provide advanced protection to photovoltaic systems by utilizing Mersens optimized dynamic thermal disconnection system, which does not require additional overcurrent protection (back-up fuse) due to its high short-circuit withstand rating. The devices are suitable for all PV applications: large-scale and rooftop. The series includes specific multipole products for multiple MPPT inverters. Features
Lightning impulse current (10/350 us): 5kA
Maximum discharge current (8/20?s): 40 kA
Nominal discharge current (8/20?s): 20 kA
Ucpv: 1060 Vdc
Iscpv: 10 kA (EN 50539-11), no back-up fuse required
DIN-rail mountable, plug-in format
Multiple MPPT specific products
Visual and remote end of life indicators
Reversible chassis to allow cable entry from above or below
Mechanically coded cartridges to avoid cartridge replacement errors
Applications
