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.

(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.

Misoperation
Misoperation caused by
the grounding of the
zero line at the load side
of the residual current
operated circuit breaker
The zero line at the load side of
the residual current operated
circuit breaker is grounded, which
may cause misoperation when the
