Intelligent control:can assign protection functions to output relays,support RS485 remote communication
Flexible installation:Supports DIN track or embedded installation,compatible with 35mm track standard
Product details
1.Hardware architecture and functional modules
Version Differences:
Type A:Basic version,only supports front panel adjustment
Type B:Increase the zero-sequence current input and RS485 communication interface
Type C:Expand digital input(V1/V2)and output relay(P3/P4)based on Type B
Enter configuration:
Three-phase current input(L1/L2/L3),supports external TA access(special TA is required when the setting current is>80A)
Auxiliary power input(A1-A2 terminals,voltage range compatible with AC/DC 24-240V)
2.Core protection logic
General protection:
Overload protection:dynamic calculation based on thermal time constant,supporting multi-stage delay adjustment
Overcurrent protection:instantaneous or short delay response,threshold value can be configured(1-2000A)
Ground fault protection:zero-sequence current detection,adjustable sensitivity(0.1A-10A)
Special protection:
Start timeout protection:Monitor the motor start time,trigger tripping when the limit is exceeded
Phase loss and imbalance protection:detect the difference in three phase current,the threshold value can be configured(5%-50%)
Control functions:
Number of startups:The number of allowed startups can be set to prevent frequent starts and stops causing equipment damage
3.Intelligence and communication capabilities
Local interaction:
The front panel LED indicator light displays the operating status in real time(such as overload,fault,communication status)
LCD screen and keyboard support parameter query and setting value modification
Remote control:
RS485 interface supports Modbus protocol and can be integrated with SCADA system
Remote reading of measured values(such as three-phase current,temperature),modifying protection thresholds and triggering trip
