Product Description

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.

Featured:

* Nominal discharge current In(8/20 us): 20 kA

* Max. discharge current Imax (8/20 us): 80 kA

* Max. continuous operating voltage Uc: AC 880 V

* Selectable circuit protection modes: 3P + 1P

*Utilizes advanced spark gap & MOV hybrid technology with reliable follow-current interruption

capability

* Integrated thermal disconnect protection with remote alarm contact (NPG)

* Modular plug-and-play design (VPM series) / Robust integrated construction (VPH series)
