Rated Parameters:
Rated Current(In):Depending on the model,this may be within a specific range(e.g.,630A-1600A;specific configurations must be confirmed).
Rated Voltage(Ue):Typically 400VAC(three-phase)or 230VAC(single-phase),suitable for low-voltage power distribution systems.
Short-Circuit Breaking Capacity(Icu/Ics):This may reach 70kA(based on the”70″prefix in the model number),meeting the requirements of high short-circuit current scenarios.
Protection Functions:
Overload Protection:An electronic trip unit provides inverse-time characteristics to protect motors and lines from overload damage.
Short-Circuit Protection:Instantaneous or short-delay tripping quickly interrupts fault current.
Ground Fault Protection:Optional,detects line-to-ground leakage current for enhanced safety.
Undervoltage/Overvoltage Protection:Detects voltage anomalies to prevent equipment damage.
Intelligent Functions:
Measurement and Monitoring:Built-in measurement of current,voltage,power,energy,and other parameters supports real-time monitoring and data analysis.Communication Interface:Supports industrial protocols such as Modbus,Profibus,and EtherNet/IP,allowing integration into SCADA or energy management systems.
Zone Selective Interlocking(ZSI):Coordinates operation with upstream and downstream circuit breakers to minimize the scope of power outages.
Energy Management:Optimizes power usage and reduces energy costs.
Mechanical Parameters:
Number of Poles:Based on the model,it is likely 2-pole(subject to confirmation);3-pole and 4-pole versions are also available.
