GADA Electric tells you how many kinds of surge protectors

- Aug 03, 2019-

Surge protector, also known as lightning protection device, is an electronic device that provides security protection for various electronic devices, instruments, and communication lines.

The standard surge protector delivers current from the electrical outlet to multiple electrical and electronic devices plugged into the power strip. If a surge or spike is generated and the voltage exceeds an acceptable level, the surge protector can conduct shunting in a very short period of time, thereby avoiding damage to other equipment in the loop.

Depending on the selected surge protector and the expected environmental impact, the protective measures required to protect the system's power supply and equipment are divided into three levels.

Class B surge protector: nominal discharge current In, impulse voltage 1.2/50 μs impulse voltage and maximum inrush current Iimp, Iimp waveform is 10/350 μsUp maximum 4kv (IEC61643-1; IEC 60664-1)

Class C surge protector: nominal discharge current In, impulse voltage 1.2/50 μs impulse voltage and maximum inrush current Iimp test, Iimp waveform is 8/25ms

Class D surge protector: test for hybrid wave bonding (open circuit voltage 1.2/50 μs impulse voltage, Denglu current 8/25 μs)
