Product overview
This is a power surge protector with three-phase in second stage, adopts common-mode protection of phase-to-ground (PEN), which is suitable for installation at the junction of LPZ1 area and LPZ2 area
Main characteristics
Module self-locking function to avoid the loss of protection because loose
Plug-in modules for easy replacement.
The base is with pre-connected wiring, easy to wire
