Product Information
- Type: Type 1+2 (T1+T2) AC surge protective device
- Maximum continuous operating voltage (Uc): 880V AC
- Lightning impulse current (Iimp): 12.5kA (10/350 μs)
- Maximum discharge current (Imax): 80kA (8/20 μs)
- Voltage protection level (Up): ≤ 3.4kV
- Standard Compliance: EN/IEC 61643-11

Application:
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.
