Description
The TZG40‑PV is a 2-pole surge protective device (SPD) designed for 1000V DC systems, commonly used in solar PV installations. It provides overvoltage protection by diverting surge currents caused by lightning or grid disturbances. Voltage Rating: 1000V DC Poles: 2 (protects both positive and negative DC lines) Discharge Capacity: 20kA nominal, 40kA maximum (8/20μs waveform) Mounting: DIN rail Application: Protects solar panels, inverters, and DC circuits from transient overvoltages Standards: Complies with IEC/EN 61643-1
