Surge Protector Selection Parameters

Maximum continuous operating voltage (Uc): refers to the maximum voltage that the surge protector can withstand under normal working conditions. When selecting a surge protector, ensure that its maximum continuous operating voltage is greater than the nominal voltage of household electricity.

Maximum discharge voltage (Umax): refers to the maximum voltage that the surge protector can withstand under specified test conditions. This parameter determines the intensity of disasters such as lightning and surges that the surge protector can withstand.

Impact current (Iimp): refers to the maximum impact current that the surge protector can withstand under specified test conditions. The size of the impact current is directly related to the protective effect of the surge protector.

Response time (Td): refers to the time from the start of action to the complete absorption of excess energy when the surge protector senses a transient overvoltage. The shorter the response time, the better the protection effect on electrical equipment.

Connection method and installation location: The connection method of the surge protector should be consistent with the connection method of the household power system, and should be installed near the distribution box to ensure effective protection of the entire household's electrical equipment.
