New Design DC power surge protective device
Contact:
This DC surge protective device is protect against DC power line system and other equipment from over voltage and instantaneous over voltage damage. Widely used in photovoltaic combiner box, power inverter, DC distribution cabinet etc. It has advantages of large discharge current, fast respond time, low residual voltage.
Features
1. Plug-in type surge protective device
2. Visible window, green means normal, red means fault
3. Double protection of fusing and over-current
4. Remote signal interface that realize remote control
