White 63A MCB Three Phase Mini Circuit Breaker 4 Pole RCBO
UKB7LE series RCBO is used for the protection against electrical leakage in the circuit of 50Hz or 60Hz,rated voltage 1 phase 230V and 3 phase 400V,rated current up to 63A ,
1. When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value,the RCD can cut off the power within the time of 0.1s automatically protecting the equipment from the fault resulted by the residual current.
2. With this function,the RCD can protect the circuit against overload and short circuit or can be used for the unfrequented switch over of the circuit under normal conditions. It conforms to IEC60898 & IEC61009.1.
3. This RCBO have 30ma 100ma 300ma and 500mA protect against leakage current.

Normal working condition and installation condition:
a. Ambient Air temperature: Ambient air temperature range from -5°C ~+40°C ,not exceeding 35°C averagely in 24 hours.
b. Location: installation location can not exceed 2000 meters above sea level.
c. Air condition: Relative humidity in the installation place can not exceed 50% when the air reaches the highest temperature +40°C , the average minimum temperature when it is the wettest can not exceed 25°C Relative humidity not exceeding 90%.
d. Installation conditions: Magnetic field outside the installation place can not exceed 5 times of the site of terrestrial magnetism in all directions. Normally speaking, RCBO should be mounted vertically .If the operation handle puts through power source upward, there should be no notable impact and vibration in the installation place.
e. Leakage protection function of RCBO is tested and adjusted by the manufacture; users can not open the products at random during usage.
f. After using RCBO for a certain time(normally one month) , test button should be pressed once in a state of making the circuit to check
g. Whether the function of RCBO is normal and reliable (press test button once, the RCBO can break off once) . If abnormal, it should be unloaded and sent to the manufacturer to repair.
RCBO cannot be wetted or soaked by rain, snow or water during the course or transportation storage and usage.
