The VPH888 series are combined Type 1 + Type 2 surge protective devices (SPDs). Their integrated design provides coordinated two-stage protection within a single unit: high-energy impulse current (Iimp) discharge for primary protection at the LPZ0-1 boundary, followed by fine protection with low residual voltage. This makes them ideal, space-saving solutions for main power inlets and distribution boards in commercial, industrial, and critical infrastructure applications requiring maximum reliability against lightning and surge threats.
