VPD1500-40/3P (T1+T2), DC1500V SPD

VPD1500-40/3P (T1+T2), DC1500V SPD

VPD1500-40/3P (T1+T2), DC1500V SPD demonstrates high safety, reliability, and exceptional grid compatibility. It is ideally suited for renewable energy applications including photovoltaic and energy storage systems. Designed for installation in DC power distribution systems, converters, inverters, and combiner boxes within LPZ0 to LPZ1 zones, it provides reliable protection for sensitive electrical equipment against damage caused by direct lightning strikes or induced transient overvoltages.

VPD1500, DC1500V  SPD

VPD1500, DC1500V SPD

The VPD1500 series are Type 1+Type 2 surge protection devices for DC systems up to 1500V, delivering 6.25kA impulse current and 40kA maximum discharge capacity, ideal for photovoltaic and other high-voltage DC protection applications.

VPM1000-50/3N+NPG(T1+T2), AC255V/1000V SPD

VPM1000-50/3N+NPG(T1+T2), AC255V/1000V SPD

The VPM1000-50/3N+NPG(T1+T2), AC255V/1000V SPD is combined Type 1+Type 2 surge protective devices (SPDs) featuring an integrated design that provides coordinated two-stage protection within a single unit. It enables high-energy impulse current (Iimp) discharge for primary protection at the LPZ0–1 boundary, followed by fine protection with low residual voltage. This makes the series an ideal, space-saving solution for main power inlets and distribution boards in commercial, industrial, and critical infrastructure applications requiring maximum reliability against lightning and surge threats.
