The working reference temperature of RCBO is 30ºC , when the ambient temperature changes, its setting value should be corrected. If multiple RCBOs are installed in a closed box and the temperature inside the box rises, the rated current should be multiplied by the
derating factor of 0.8.
The "N" line on the RCBO should be connected to the neutral line to make the electronic circuit work normally and play a prote- ctive role.
It is not allowed to use the method of short-circuiting the phase line to the neutral line or the phase line to the phase line to carry out the short-circuit protection capability test on the RCBO.
Recommended selection principles
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.

SURROUNDING AIR TEMPERATURE:
1.The ambient air temperature shall not be lower than -5 1C, not
higher than+40 C, and the daily average value shallnot exceed+35 C.
2. Altitude: The altitude of the installation site shall not exceed
2000m.
3.Atmospheric conditions
The air is clean, and at a maximum temperature of+40 'C, the
relative humidity of the air is not high More than 50%. Higher
relative humidity is allowed at lower temperatures, such as at+20
C,
The relative humidity should not exceed 90%. Due to occasional
moderate condensation caused by temperature changes, Attention
should be paid to taking appropriate measures.
4. Installation Category Installation categories are lI and III
Current and Number of Poles
100A: This indicates that the RCBO is rated at 100 amps. The
current rating is the maximum value of current that the circuit
breaker can carry continuously without causing overheating or
damage.
2p, 4p: The “p” here stands for the number of poles, i.e., the
number of circuit phases to which the circuit breaker can be
connected. 2p means that the circuit breaker can be connected to
two circuit phases (usually Fire and Zero), whereas 4p means that
it can be connected to four circuit phases (usually three-phase
Fire and Zero).
Multifunctional
Multifunctional indicates that this 100A 2p 4p Multifunctional RCBO
is equipped with a variety of protection functions. In addition to
basic overload and short-circuit protection, it can also provide
leakage protection, undervoltage protection, overvoltage
protection, and so on. temperature protection,Water ingress
alarm,Adjustable current and voltage.These protections allow the
RCBO to provide more comprehensive protection for circuits and
equipment.
