STP T2 40 PV is the series of devices that provide advanced overvoltage protection to photovoltaic systems by utilizing Mersen’s optimized dynamic thermal disconnection system, which does not require additional overcurrent protection (back-up fuse) due to its high short-circuit withstand rating.
These surge protective devices are suitable for all PV applications:
Large-scale, rooftop and self-consumption (off-grid) DC installations.
The series includes specific multipole products for multiple MPPT (Maximum power point tracker) inverters.
Maximum discharge current (8/20μs): 40 kA
Nominal discharge current (8/20μs): 10 kA, 20 kA
Ucpv: 65, 80, 660, 1060 Vdc and 1500 Vdc
Iscpv: 10 kA (EN 50539-11), no back-up fuse required
SCCR: 50 kA, 65 kA, 100 kA (UL 1449 4th Ed.)
DIN-rail mountable, plug-in format
Multiple MPPT specific products with UL 1449 certification
Visual and remote end of life indicators
Reversible chassis to allow cable entry from above or below
