PHL-TA-20
Product overview
This SPD is a three-phase power surge protector used in the third stage, adopts the common differential mode protection mode of phase line to zero line and zero line to ground, which is suitable for installation in TT power supply system shunt distribution cabinet and the junction of other LPZ2 areas, LPZ3 areas and subsequent areas.
Main characteristics
- 1. Pre-wiring at base, convenient to wiring.
- 2. plug-in modules for easy replacement.
