Structure Features and Working Principle

This residual current operated circuit breaker primarily consists of zero sequence current transformer, electronic component board, release, contact operating mechanism, and plastic shell.

The working principle is shown in Fig. 3. In case of electric leakage or personal electric shock in circuits, when the residual operating current reaches the set value of the operating current, a signal will be generated from the secondary coil of the zero sequence current transformer (induced voltage) to open the residual current operated circuit breaker after amplification by the electronic line, thereby cutting off the power supply for electric leakage protection.

Product Accessories

There are six different accessories in the circuit breaker, including OF auxiliary contact, MX+OF shunt release, SD alarm contact, MV overvoltage release, MN undervoltage release, and MVMN overvoltage and undervoltage release. All accessories are installed on the left side of the product.

Installation, Operation and Maintenance

  • Installation and Operation
  1. Before installation, check whether the product marks is consistent with the working conditions.

  2. Press the Reset button before power-on.

  3. Before power-on, operate the residual current operated circuit breaker several times and check that its mechanism works flexibly and reliably without blockage.

  4. The input end shall be connected to the power supply, and the output end shall be connected to the load.

  5. The cross-sectional areas of the connecting wire are listed in Table 3.
    Table 3 Sectional area of the connecting wire and the rated current
    Table 3

  6. After power-on, operate the test button of the residual current operated circuit breaker to confirm whether it can work reliably.

  7. When installation, insert the residual current operated circuit breaker into the mounting rail to fix the residual current operated circuit breaker on this rail without looseness or falling off. To remove the residual current operated circuit breaker, push the circuit breaker upwards to make the upper part of the circuit breaker leave from the mounting rail for removal, or pull the stop block downward for removal.
    The working reference temperature of the residual current operated circuit breaker is +30+5 0℃. When the ambient temperature changes, its rating shall be corrected. The temperature correction coefficients are listed in Table 4; if multiple residual current operated circuit breakers are all installed in a closed box, the temperature inside the box will rise, so that the rated current shall multiply by the derating coefficient 0.8.

Table 4 Rated current and temperature correction coefficient table

  • Maintenance

After the residual current operated circuit breaker is running for some time, please check it regularly (monthly). In the power-on state, press the test button and check whether the residual current operated circuit breaker can work reliably. If failed to work normally, please stop the operation and replace it immediately
