GSP9-C40PV 600V 3P Surge Protection Device(SPD)



This DC surge protective device is applied low voltage standard IEC EN 61643-11 to protect against DC power line system and other equipment from over-voltage and instantaneous over-voltage damage. Widely used in photovoltaic comber box, power inverter, DC distribution cabinet, etc. It has the advantages of a large discharge current, fast response time, and low residual voltage. Max. PV voltage up to UCPV ≤1000V dc.

Main features:

1. High discharge capacity, quick response, module pluggable;

2. Fast response time, din rail installation;

3. Double thermal disconnection devices, provide more reliable protection; 4. Green window means normal, red means defect, need to change module;

5. Remote alarm terminal optional.

6. T1+T2 surge protection.
