1kgOur 3-series Class C SPD is applicable to 50/60Hz AC power systems up to 380V/385V, covering TN-S, TN-C-S, TT and IT configurations. It performs equipotential connection at the junctions of LPZ1, LPZ2 and LPZ3 zones.
Manufactured to meet IEC61643-1 and GB18802.1 requirements, this device features a casing compatible with 35mm electrical DIN rails. It comes with an internal fault disconnection component. Once the SPD is damaged by overcurrent, excessive heat or breakdown, the component will isolate the unit from the mains automatically. The visible alarm light will turn from green (normal) to red (error). The module can also be replaced while the system remains energized.
