Mersen, STPT2 Surge Protection Device 530 V dc Maximum Voltage Rating 40kA Maximum Surge Current Type 2 Mersen SPD

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.
