Short-circuit protection SWL350 to provide short to produce the motor over-current protection. The over-current protection by independent components, each component can be started individually, action time can be set according to site-specific circumstances. Stall protection in the motor running to provide protection components by overheating, the motor starts automatically identifies current process of change by providing protection, this will allow for start-up time is longer but the time course of motor stall provides fast protection. When the motor during startup if the current decline is not obvious, resulting in starts stall protection, overload protection is also recognized by the state and stall protection. Thermal overload protection when the value reaches 100% capacity, overload protection trip. Full account of the heat capacity of the positive sequence, negative sequence current generated by the integrated thermal effects, the current real test to ensure the effective harmonic thermal effects on the correct response. Provide a definite time protection components and inverse time overload protection to meet the different needs of the scene. Phase current unbalance protection SWL350 monitor the ratio of the motor phase current unbalance, phase current imbalance if the value is greater than the alarm for 5 seconds and then the alarm; if the phase current imbalance is greater than the trip value, and for 5 seconds, then given trip. Undervoltage protection for voltage sensitive loads (such as induction motors), voltage drop will increase the sink, which may cause motor overheating occur within very dangerous, when the voltage drops to a preset voltage setting value, after a preset time delay, under-voltage protection will trip an alarm or command. Overvoltage protection is running at a constant load of the motor, over-voltage can cause current drops. However, iron loss and copper consumption will cause an increase in motor temperature. In this case current overload relay will not function, can not provide suitable protection, so the continuous over-voltage conditions, this motor will provide overvoltage protection devices. Earth / ground fault leakage protection value is the value as a percentage of the value of CT measurements. Ground current detection scheme based on zero sequence CT. To prevent false alarms caused by transient inrush current, this feature can be set in a time delay. The ground fault protection function provides an alarm or a fault trip, ground alarm can damage the insulation to provide a pre-warning. Protection device start-up time is too long to start the process of automatic identification of the motor, the required start-up time is not completed within the motor starts, the protection action. Under voltage auto-restart feature is enabled, the motor in an instant loss of power, since the launch of start time, if the low-voltage protection is activated, the entire set from start-up time before the arrival of the voltage back to 90% of the rated voltage or more, then send motor closing command.
