SDRNL Mini RCD​ Earth Leakage Circuit Breaker with Overload Protection 10~40A 1P+N for AC230/400V Use

SDRNL earth leakAge circuit breakers aremainly applied to the AC 50/60Hz 1Hz circuit rated 240V and 32A or below, They have the
electric leakAge(electric shock),overload,short circuit and so on protection functions . the over voltage protection functions.

The over voltage protection function can also be provided upon requirements.

They are mainly used to protect the buiding illumination and power distrion system.

Normal Operation Conditions
●Ambient Air temperature:Ambient air temperature range from -5℃ ~+40℃ ,not exceeding 35℃ averagely in 24 hours.
●Location:installation location can not exceed 2000 meters above sea level.
●Air conditons:Relative humidity in the installation palce can not exceed 50% when the air reaches the highest temperature +40℃ ,
the average minimum temperature when it is the wettest can not exceed 25℃ Relative humidity not exceeding 90%.
●Installation conditions:Magnetic field outsid 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.
●LeakAge protection function of RCBO is tested and adjusted by the manufacture,users can not open the products at random during usage.
After using RCBO for a certain time(normally one month) , test button should be pressed noce in a state of making the circuit to check
whether the function of RCBO is normal and reliable(press test button once, the RCBO can break off noce) . If abnormal, it should be
unloaded and sent to the manufacturer to repair.
●RCBO can not be wetted or soaked by rain,snow or water during the course or transportation storage and usage.
