NU6-2G series surge protector
NU6-2G series surge protector is suitable for AC 50Hz, rated voltage is single-phase 230V/ three-phase 400V power distribution and control system, meet the SPD class II test, used to suppress the transient overvoltage below the equipment withstand impulse overvoltage, discharge surge energy, so as to protect the system circuit and equipment. It is suitable for hierarchical coordination with other series of surge protectors to achieve layered protection system, so that the low-voltage distribution system can be more extensive and more effective protection.
Selection of surge protector
The selection of surge protectors should follow the following principles:
The voltage continuously applied between the terminals of the surge protector should not be greater than the upper limit of the continuous working voltage Uc of the surge protector.
The voltage protection level Up of the surge protector should be less than the shock tolerance limit of the protected equipment; Select specifications according to different grounding systems and protection modes.
