I want to make an inquire■ Compact Design
■ MCU( Microprocessor Control Unit ) Based
■ Three Integral Current Transformers
■ Multiple Protection Functions
■ Digital Ammeter/3 Phase Current Display
■ Troubleshooting/Trip Cause Memory, Display
■ Adjustable Operating Features by Mode switch
■ Wide Current Adjustment Range
■ Selectable Time-Current Characteristics(Inverse/Definite)
■ Manual(Instantaneous)/Electrical(Remote)Reset
■ Test Function
■ Ambient Insensitive
■ Selectable Fail-safe and Non-fail-safe Operation Modes
■ Inverter (20~400Hz)
