          LSKM6 series electric energy meter external circuit breaker is an automatic reclosing miniature circuit breaker specially designed for communication and electric power with the function of automatic tripping and closing.The breaker is applicable to the line of  AC 50Hz, rated voltage to 400V, rated current to 125A, mainly used with cost control electric energy meter. It not only can solve the problem that the power supply cannot be automatically restored after the switch trips due to arrears, and realize the function of “remote control”, it can also protect the electrical equipment and the line according to the current short circuit and overload operation of the power supply line.

          The breaker meets the standards GB 10963.1-2005 and QGDW11421-2015, etc.

          The maximum temperature is no more than 50% at +40, and higher relative humidity at lower temperatures, such as 90% at +20.

          Special measures should be taken for condensation that occasionally occurs due to temperature changes.

          Conversion operation

          Pull the switch to the automatic position. After the arrears are automatically opened, the charging will be automatically closed. If the electrical line fails, it can be manually closed.

          Pull the switch to the manual position. After the arrears are automatically opened, the charging will not be automatically closed, and manual closing is required.

          Status Indicator

          The indicator light is on, indicating that the meter is not owed, and can be divided and closed normally;

          The indicator light is off, indicating that the meter cannot be closed or the line is dead.
