ZGXL-MZ2J-5b Signal SPD
General
The ZGXL-MZ2J-5b Signal SPD can be used in industrial control internetwork, RS485/422 interface, special line, automatic control, instrument line, data line, telephone equipment, fax equipment and etc. The two-class protection is adopted, with the first class to shunt the current and the second to clamp the voltage. Once the transmission line is struck by lightning strokes and surges, the SPD will shunt the lightning and surge current to the ground, clamping it to an acceptable range of equipment, which protects the equipment.
Features
Characterized by high discharge capacity, fast response speed (ns) and low protection level, and can be installed on the 35mm DIN rail with the connection mode of terminal blocks.
