Lightning backup surge protector is designed according to IEC and GB standards, using the main circuit release technology, usually used to protect the Iimp for 25KA SPD, can cut off the amplitude of up to 100KA high short-circuit current, and can cut off the low short-circuit current of more than 3A in a very short period of time, has a high short-circuit breaking, low short-circuit transient, high surge withstand capacity, low residual voltage, small size, can be monitored, etc., widely used in power distribution cabinets, distribution boxes, low voltage cabinets SPD backup protection. Widely used in distribution cabinets, distribution boxes, low-voltage cabinets SPD backup protection.
