- Industrial and civil electrical systems: NJYB3 Relay can be used to protect electrical equipment, machinery, and systems in buildings, factories, workshops, substations, and other industrial applications from voltage-related problems such as overvoltages, under voltage, three-phase imbalance, and excessive temperature.- Control and Automation Systems: In automation applications, NJYB3 Relay can be used to monitor and protect voltage equipment such as motors, pumps, fans, and other electrical equipment. It can turn off the device when unwanted voltage problems are detected.- Renewable Energy Power Systems: In systems that use renewable energy such as solar and wind, NJYB3 Relay can help ensure that voltage is properly supplied and controlled to optimize performance and protect components.- UPS and Load Control Systems: Relay can be used to protect critical equipment such as UPS (Uninterrupted Power Supply System) and critical loads from voltage-related problems.- Production Control System: During manufacturing processes, NJYB3 Relay can help protect equipment and ensure that machines operate stably under safe voltage conditions.
