Are the functional characteristics of surge protective devices clear?

Surge protector, also known as lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When peak current or voltage is suddenly generated in electrical circuit or communication line due to external interference, surge protector can conduct shunt in a very short time, so as to avoid the damage of surge to other equipment in the circuit. Lightning arrester
Function of lightning arrester
The over-voltage protector for indication alarm is mainly used for the protection of 220V power supply system. The product has single arbitrary combination, double grounding and single-phase power supply full mode protection.
Characteristics of lightning arrester
Large absorption ability (5ka-40ka), low limiting voltage;
Fast response speed (< 25ns);
Any module can be replaced at any time, and maintenance is convenient.
Double monitoring and isolation device with thermal fuse and current fuse control; lightning rod
With remote monitoring alarm terminal;
Window red is fault status;
The combined structure can easily realize the design of different protection modes.
