Function and Application
The NS5 series motor starter is mainly used in AC circuits with a frequency of 50Hz (or 60Hz), operating voltage up to 690V, and operating current up to 32A, as overload, phase failure, short circuit protection, and infrequent starting control for three-phase squirrel cage induction motors. It can be used for distribution line protection and infrequent load switching, and can also be used as an isolator.
