Product Information

General Instruction

      NSR - 3770 series low voltagemotor integrated protection device is a kind of motor intelligent protectiondevice developed base on microprocessor technology, it provides for low voltagemotor a complete set of specialized and intelligentized management solution,which integrates protection, measurement and control, it is an ideal choice forthe motor intelligent management of process control system.

The models of NSR-3770 series low voltage motor integratedprotection device equipped, including of NSR - 3771, NSR3772, NSR - 3773, NSR -3774, NSR - 3775, etc., can meet the protection and management demands of the380v low voltage system motor in different application scene. Each type ofdevice can complete a variety of protection function and provide kinds of eventrecords and query, it makes the scene operation and management more convenient.Through the scene bus technology to realize data exchange, sent all kinds ofoperation information and fault records to the control center, or independentlyconstitute low voltage control system.

NSR - 3770 series low voltage motor protection can bewidely used in petroleum, chemical, electric power, steel, metallurgy, paper making,textile, cement and so on of different industrial fields.
