Why Choose the Mersen 83020159 Photovoltaic Surge Protection Device?
The Mersen 83020159 STPT2-40K1500V-YPVM is a high-performance Type 2 photovoltaic surge protection device (SPD) designed to protect DC solar PV installations from transient overvoltages caused by switching operations and indirect lightning activity. As part of the Mersen Surge-Trap® Pluggable STPT2 Series - YPV, it provides dependable surge protection for commercial, industrial and utility-scale photovoltaic systems.
This pluggable PV surge arrester is engineered for straightforward installation, fast cartridge replacement and reliable long-term protection of sensitive solar equipment. The integrated remote indication feature allows the SPD status to be monitored from external systems, helping maintenance teams identify end-of-life conditions quickly.
With a 40 kA maximum discharge current, 1500 V DC rated photovoltaic voltage and three-pole Y PV configuration, the Mersen 83020159 is ideal for modern high-voltage photovoltaic installations. Its compact three-module DIN rail format makes it suitable for solar combiner boxes, inverter input protection and PV distribution enclosures.
