5.1 General selection principles
a)The rated working voltage of RCBO ≥ the rated voltage of the line.
b) The rated current of RCBO is 1.1-1.25 times the load current calculated by the line.
c)The rated short-circuit breaking capacity of RCBO ≥ the maximum short-circuit
current that may appear in the line.
d)RCBO instantaneous release setting current ≤ 0.8 times the end of the line phase
-to-ground or phase-to-phase short circuit current.
e) Single-phase rated current of electric heaters, refrigerators and incandescent la-
mps at a given voltage and power In=P/U; three-phase rated current In=P/1.732U.
RCBO residual current is generally selected as 30mA, which is used as personal
contact protection.

storage and use.
2. Before installation, check whether the basic technical data of the signs and signs
meet the requirements (the selected current The size should match the actual use):
manual operation several times should be flexible, confirm that it is intact, Installation:
When installing, wires that can withstand the corresponding current carrying capacity
should be selected. See attached table 3 for reference values.
3. Strictly follow the wiring diagram for installation.
4. Run check: 4.1 Check whether the wiring is correct, especially check that the
input terminal of the leakage circuit breaker should be connected to the power supply,
and the output terminal should be connected to the load.
4.2 Confirm that the screws of each terminal have pressed the wire tightly, and the wire
should be in the corresponding wiring frame.
4.3 Close the leakage circuit breaker and press the test button to check whether the
leakage protection performance is normal and reliable. If the leakage circuit
breaker can be disconnected normally, the indicator will be red.
5. After the leakage circuit breaker has been running for a certain period of time
(usually one month), it is necessary to press the test button in the closed and energ-
ized state to check whether the leakage protection performance is normal andreli-
able (press the test button once a month, and the leakage circuit breaker should be
broken once). In case of failure, it should be removed and sent to the manufacturer
for repair.
6. The neutral wire () at the outlet end can only be used as a working neutral wire, not
a protective neutral wire. 7. When the leakage exitable model is selected, the leakage
"exit" function of the circuit breaker is an emergency use function, which is only used
by professional power supply maintenance personnel in emergency maintenance situations.
After maintenance, it must be put into leakage protection function status immediately.
