Function |
Circuit breaker (Air switch) |
80A |
When the current of the protected,circuit exceeds the specified value,the circuit breaker will automatically break off to protect the whole circuit. |
Fusegear |
80A |
When the current of the protected circuit exceeds the specified value,fusegear will break off automatically |
Surge protective device (SPD) |
UC:420V lmax:20KA
In: 10KAUp≤1.8KV |
Photovoltaic lightning protection device |
One phase self dual over voltage protection device |
Working range 220V,50Hz,
over voltage protection
Uvo=270V±5V
