Publish Time:2019-06-14 Author:admin Views:0
- High-performance microcontroller (MCU) is generally used for signal processing and intelligent control in real time;
- LCD Chinese display, friendly man-machine interface, easy to operate;
- Residual current (leakage) protection, residual current gear can be set online, delay type and non-delay type can be arbitrarily selected;
- Has a reclosing function;
- Automatic tracking, automatically adjust the gear position according to the residual current of the line to ensure the operation rate and reliability of the product;
- Long delay, short delay and instantaneous three-stage protection, current can be set, electronic tripping, independent of power supply voltage;
- High breaking capacity to ensure the reliability of line short circuit protection;
- Large current instantaneous tripping function, when the circuit breaker is closed, encounter short circuit and large current (≥20Inm), the circuit breaker is directly tripped by the electromagnetic trip mechanism;
- Overvoltage protection, undervoltage protection, phase loss protection;
- Leakage does not trip alarm output function;
- Real-time display of line residual current, three-phase power supply voltage and load current;
- Protection functions and parameters can be modified online;
- Fault record, record the total number of trips, query the cause of the similar 10 trips, fault parameters when tripping, trip time;
- The network type has a communication function, which can realize remote signaling, telemetry, remote control, and remote adjustment.
