Core Functions

1. Collect current and voltage signals from CT and PT sensors, implement multi-protection logic including overload, phase loss, overcurrent and ground fault protection.
2. When motor operating condition exceeds preset threshold, trigger relay trip output to cut off motor power supply and avoid motor winding burnout.
3. Built-in event recording function saves fault time, type and parameter data, convenient for post-fault analysis of motor abnormal operation.
4. Front LCD screen and keypad support local parameter setting, real-time data browsing and fault code checking for on-site commissioning.
5. Communication interface connects to DCS and SCADA system to realize remote motor status monitoring and alarm information upload.
6. Compact panel mounting design can be installed directly on the motor control cabinet, suitable for transformation of old motor protection systems.

Application Scenarios

1. Motor protection unit for medium and low voltage motors used in power, mining, water treatment and chemical industry.
2. Fault protection relay replacement and routine maintenance of existing Bently Nevada 369 series motor control cabinets.
3. Motor protection hardware upgrading and technical transformation for aging legacy industrial motor control systems.
4. Emergency swap for relay failure of important motor equipment requiring complete electrical protection and fault recording.
5. Spare-parts stocking for electrical maintenance teams supporting Bently Nevada 369 motor protection series products.
6. Aftermarket spare supply for motor control cabinet overhaul and technical-service projects of heavy industrial facilities.

FAQ

1. Q: Can Bently Nevada 369-HI-0-M-0-0-0 relay work independently without CT, PT and motor circuit breaker?
   A: It needs CT/PT signal input and matched trip circuit breaker, cannot run as standalone hardware.
2. Q: What are typical relay failure symptoms?
   A: No measured data display, false trip, communication interruption, unable to save fault event records.
3. Q: How to complete commissioning and diagnosis?
   A: Check CT/PT wiring and power supply; configure protection parameters, test alarm and trip function and verify communication connection.
