AC 2P 4P 1P+N/PE 3P+N/PE 15KA~80KA Surge Protective Device SPD
CAU4-230 Surge Protective Device
CAU4-230 series SPDs are applied in 230/400V (50/60Hz) low-voltage power supply and distribution systems such as computer room equipment, monitoring room equipment, fire control room equipment, telephone room, other low-voltage rooms, offices, and household electrical equipment forpreventing them from indirect lightning strike and surges. They are used in the potential connection like the lightning induction prevention betweenLPZ02 and LPZ03 interfaces.
