Questions about this product
- What is this DC surge protector used for?
- It clamps voltage spikes on high-voltage DC lines so they don't fry your gear. People mainly fit it on solar PV arrays and DC industrial circuits. It reacts in nanoseconds and sends surge current safely to ground.
- What DC voltage and DIN rail does it fit?
- The maximum continuous operating voltage is 1000V DC, and model variants cover 500V, 800V, and 1000V. It snaps onto standard 35mm symmetrical DIN rail (TH35). Pick the model that matches your system's DC voltage.
- How much surge current can it actually handle?
- Nominal discharge current (In) is 20kA and maximum discharge current (Imax) is 40kA on an 8/20 microsecond wave. That covers most lightning-induced and switching transients on a typical solar or DC circuit. It protects both the positive and negative lines.
