Overview wifi circuit breaker

M7C series residual current operated circuit breaker mainly used in three phase four wire circuit with AC 50Hz or 60Hz, rated voltage 440V, rated current to 800; except the protection of overload or short-circuit, it also has the protection of residual current , over voltage, under voltage, the phase-lacking, faulted neutral line(optional) and so on.The product with high level of performance is easy to use, and it can be used to display the current voltage, current, residual current, trip reason and phase intuitively.You can choose to have a RS485 communication interface, transfer of circuit breaker opening or closing state, the trip analysis, the voltage and current of each phase and the residual current circuit breaker’s data; also can remotely set the protection action value and action time,can enable or disable the various protection functions.

All technical indexes are in conformity with GB14048.2-2008,GB6829-2008,Q/GDW11196-2014,Q/GDW11020-2013,CCC;and have passed the authoritative testing by Chinese EPRI of conventional function, residual current and special environment action characteristics, lightning protection module, communication function, scholte wave functions and technical parameters .

Functions

1. High-performance single-chip control program, and advanced LED digital display. Accurate action and High precision. It can be displayed digit alphanumeric.

2. Limit short-circuit breaking capacity can be up to lcu 85KA.

It has High breaking capacity, small volume, nice appearance, short flash-over distance.

3. Our product has won state invention patent such as design and other utility model patents.

4. It has Anti-interference ability. It adopts advanced anti-lightning residual voltage circuit and high strength transient protective device, resists lighting induction effectively and eliminates all interference.

5. The overload, overcurrent, undervoltage, residual current, short circuit, grounding protection function and manual, automatic reclosing together, ensuring electricity environment, equipment and personal safety.

6. Network management and remote monitoring could be realized With RS485 communication interface and intelligent digital control technology; . Also can transmit fault trip signal to the mobile phone of the electrical engineering on duty based on the needs of users.

7. With automatic and manual operation also can carry on the remote operation according to the user needs.

8. It can display the product trip reason and it is convenient for the accurate maintenance.

9. It can be used with smart meter, magnetic type ammeter, prepaid card device, and as the operating components of power outages, power supply.

10. In case of the accident caused by leakage with tripping function.
