2P 1000V DC 40kA Surge Protection Device – Type 2 Solar SPD for PV Systems
This 2-pole 1000V DC surge protector device (SPD) is designed to protect photovoltaic systems against transient overvoltages caused by lightning strikes and switching operations. With a maximum discharge current (Imax) of 40kA and a nominal discharge current (In) of 20kA, this Type 2 surge arrester effectively limits voltage spikes to safe levels for sensitive PV equipment, including combiner boxes, inverters, and MPPT charge controllers. The built-in thermal disconnector ensures safe failure mode, while the visual status window provides instant indication of protection status.
