1. Product introduction
CAU4-40R series SPDs for bulit-in fuses are applied in 230/400V (50/60Hz) low-voltage power supply and distribution systems such as computer room equipment, monitoring room equipment, control room equipment, telephone room, other low-voltage rooms, offices, and household electrical equipment for preventing them from indirect lightning strike and surges. They are used in the potential connection like the lightning induction prevention between LPZ02 interfaces.
