Product overview
A three-phase power surge protector for the second level, using a common mode protection mode of phase line to neutral line and neutral line to ground, suitable for installation in TT power supply system The branching distribution cabinet, as well as the junction of other LPZ1 and LPZ2 zones and subsequent zones.
Main characteristics
1. Pre connected base for easy wiring
2. The 'lightly press' function of the module allows for easy insertion and removal, making it easy to replace.
