Class 2 Open Cage Polymeric
from only POA
- Protection of MV networks, sensitive equipment and substations from lightning and switching surge related over-voltages in areas with relatively high iso-keraunic levels.
- Direct moulded housing to prevent moisture ingress
- Low residual voltages
- High-energy handling
- Superior TOV performance
- Safe non-shattering short current behaviour to higher current levels
- The crimped structural construction ensures light weight product with optimal mechanical strength
- Maintenance free
- Hydrophobic silicon housing (tracking and erosion resistant)
- Tested in accordance with IEC60099-4 at independent accredited laboratories
