DST-S120/2P-385FM type surge protector

Classification:

Power surge protector

DST-S120 surge protector is suitable for AC 50Hz/60Hz;220V/380V power supply system, which can be used as the low-voltage general distribution of building incoming lines. The electrical system provides the first level of lightning protection. Such as the building's low-voltage main power distribution cabinet, outdoor power distribution control cabinet and the high risk of lightning power primary protection Ray system. The maximum discharge current is 120kA.
