Product overview
A third stage power surge protector, suitable for installation in various types of power supply distribution box terminal, and the other junction between LPZ2 and PLZ3 zones and subsequent partition of the region.
Main characteristics
Module self-locking function to avoid the loss of protection because of loose；
Plug-in modules for easy replacement.
