Aspa Solar PHOENIX CONTACT SOLAR AC SPD 3 PHASE 4P AC SURGE PROTECTOR

Phoenix Contact AC SPD (Surge Protective Device) is designed to protect electrical systems from transient overvoltages caused by lightning strikes or other disturbances.
Uc (Voltage Protection Level): 335V AC Uc represents the maximum continuous voltage that the surge protector can withstand without breakdown or degradation. In this SPD it is 335V AC.
Up (Voltage Let-Through): 1.5 kV Up is the voltage protection level or the maximum voltage that the surge protector allows to pass through to the protected system during a surge. In this case, it is 1.5 kV.
In (Nominal Discharge Current): 20 kA In represents the maximum surge current that the surge protector can safely dissipate without performance degradation. In this spd, it is 20 kA.
Imax (Maximum Discharge Current): 40 kA Imax is the maximum surge current that the surge protector can withstand without failure. In this spd, it is 40 kA.
Defective display appears:- If the red “defective” display appears, the plug is damaged. Replace the plug with a plug of the same type, make sure that you remove the coding plate before using the replacement plug, if the base element is damaged, you must replace the product completely
