- Discharge overvoltage protection for switch-type (8/20μs) over currents
- Suitable for TN-S electrical systems
- Lightning and overvoltage protection in AC 50/60Hz networks
- Protection of low voltage power networks from lightning or surge overvoltage
- Designed for installations with reduced direct lightning strike risk
- Used in addition to SPD Type 1 for enhanced voltage limitation
- High discharge current capacity (40kA)
- Low voltage protection level for superior performance
- Interchangeable varistor modules for easy maintenance
- IP20 protection rating for environmental safety
- Advanced high-energy varistor technology
- Type 2 arresters must be installed in sub-distribution boards after main distribution boards containing Type 1 arresters
- Minimum 10-15 meter cable distance required between Type 1 and Type 2 arresters
- Decoupling coil installation required if distance requirements cannot be met
- Additional protection systems recommended in areas with frequent storms
