Working Principle
This surge protection device operates as a voltage-limited port protection system. When normal operating voltage is present, the device remains inactive. During lightning strikes or transient overvoltages, the arrester immediately diverts the high-voltage current to ground, protecting connected electrical equipment. The 3P+NPE configuration includes three phase protection modules plus a neutral-ground protection module, making it suitable for TN-S and TT power supply systems.
Key Features
- Strictly screened core components for reliable performance
- Advanced arc extinguishing technology prevents fire hazards
- Modular design for easy installation and maintenance
- Built-in thermal disconnector with visual failure indication
- Automatic disconnection from power grid upon failure
Installation Guidelines
Ensure grounding lines are short, thick, and straight to minimize distributed inductance effects. The device must match the protected equipment's working voltage and should be installed according to the provided installation sketch.
