Smart Metering MCCB

The product can not only provide indirect contact protection, and effectively prevent fire hazards caused by device insulation damage and ground fault current generation, but also can be used to distribute electric energy to protect lines and power devices from overload, under-voltage, short circuits, single-phase grounding and other faults. In addition, the built-in high-precision measurement device realizes high-precision and reliable power measurement and power quality data detection. Support infrared and RS485 communication functions, and can also plug in standard communication modules to support 4G, HPLC, WIFI communication, support cloud platform, and realize remote signaling, telemetry, remote control, and remote adjustment.

Function and Features

1) High-performance 32-bit ARM microprocessor is used for real-time signal acquisition and processing.

2) Double CPU double protection electronic tripping, high breaking capacity design. Long-delay, short-delay, and instantaneous three-stage protection can reliably perform overcurrent and short-circuit protection functions when the line voltage is abnormal. Long-delay supports current inverse time limit operation to ensure the reliability of line protection.

3) Supports short circuits, overvoltage, overcurrent, overload, overtemperature, phase loss, unbalance, neutral loss (only three-phase unbalanced loads support), and residual current protection. Various protection functions and parameters can be set and modified online.

4) Support fault automatic reclosing function, close function, close delay, and close times can be configured.

5) Built-in high-precision measurement dedicated chip, supports high-precision current, voltage, active power, reactive power, and apparent power measurement, and the energy measurement accuracy can reach 0.5. It can display various electrical parameters, alarm information, and operating status in real time.

6) Real-time monitoring of the residual current of the line, and the fastest time of holding action can reach 0.05 seconds. The residual current gear can be adjusted online and supports adaptive tracking adjustment of the residual current gear.

7) Support power quality analysis function, which can monitor grid frequency, harmonics, unbalance and support real-time display of current and voltage waveforms of each phase.

8) Support the function of accumulating electricity in sharp, peak, shoulder, and off-peak, and support two-way energy statistics.

9) Equipped with the temperature detection function of the upper and lower terminals, the accuracy is ±1°C, and line heating protection can be performed.

10) Support infrared and RS485 communication functions, and can also plug in standard communication modules to support 4G, HPLC, WIFI communication, support cloud platform, and realize remote signaling, telemetry, remote control, and remote adjustment.

11) Perfect log system, parameter modification, fault protection, and opening and closing control can be recorded and queried.

12) LCD menu design, multi-language support, ON/OFF and status indicators, friendly man-machine interface, easy to operate.
