The Mersen 83020138 STPT2-40K600V-YPV is a reliable 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 rooftop, commercial and industrial photovoltaic systems.
This pluggable PV surge arrester is designed for straightforward installation, fast cartridge replacement and long-term protection of sensitive solar equipment. Its modular construction helps reduce maintenance time, while visual status indication allows the protection condition to be checked quickly during inspection.
With a 40 kA maximum discharge current, 600 V DC rated photovoltaic voltage and three-pole Y PV configuration, the Mersen 83020138 is suitable for DC-side surge protection in photovoltaic power systems. Its compact three-module DIN rail format makes it ideal for solar combiner boxes, inverter input protection and PV distribution enclosures.
Photovoltaic surge protection devices are installed on the DC side of solar power systems to limit transient overvoltages before they reach sensitive equipment. They help protect PV strings, combiner boxes, inverter inputs and monitoring equipment from damaging voltage spikes.
The Mersen STPT2-40K600V-YPV combines strong surge discharge capability with a practical pluggable construction, making it a dependable choice for solar installers, electrical contractors and maintenance engineers working on photovoltaic power installations.
