A double-wave rectified voltage is generated. The same applies when multiple electromagnetic circuits and disconnectors are used. This load resistance R
The voltage across the is applied to a voltmeter M that has a scale that converts the DC voltage into a current as necessary, and the load current is read by converting it into a current. Monitoring can be done in a centralized manner. Further, by extending the connection line of the voltmeter M, remote monitoring becomes possible.

The vertical axis shows the rectified voltage of the voltage coil 9, and the horizontal axis shows the % of the rated current of the circuit breaker. Therefore, if the load resistance R is selected within the range of 100KΩ to 22KΩ, it will be appropriately included in the region E. Note that the curve curves when the percentage of the rated current is less than 40%, but since it is converted to current, there is no problem, and it is usually used when the percentage is 5% or more.
