The YCS6-D 1P SPD is a single-pole surge protection device engineered for low-voltage AC power systems up to 230/400V. With a discharge current capacity of 5–10kA, it protects sensitive electronics from transient overvoltages and lightning-induced surges. Its 18mm slim profile allows easy integration into modular distribution boards. The yellow indicator window provides clear visual status, and the 38V triggering threshold ensures early response to voltage spikes. Compliant with IEC61643-1 and IEC60898, it’s suitable for TT, TN, IT, and TN-C-S systems and ideal for use at LPZ1–LPZ2 boundaries in residential, commercial, and IT installations.
