I want to make an inquire■ MCU( Microprocessor Control Unit )Based
■ Convenient installation
■ Full mode function:easy to set
■ Three Integral Current Transformers
■ Full cover protection Function
■ Wide Current Range protection
■ Built-in digital ammeter
■ Total running time display
■ Bar-Graph monitoring on impending overload trip
■ Selectable time-current characteristics[Inverse/Inverse based on thermal Memory (Thermal Inverse) /Definite]
■ 4~20mA current loop communcations
■ Test Function
■ Operates in wide ambient temperature range
■ Selectable Fail-safe Operation/ No volt Release(FS:ON
