Supply Residual Current Circuit Breaker

type F360 residual current circuit breaker without over current protection conforms to the standard of GB16916.1.IEC1008.BS4293 etc.it si used in the circuits of AC50-60Hz,1p230/220V,3P400/380V in industrial&mining enterprises,commercial building and housing for protection of personal electric shovk hazard and electric equipment and for unfrequent switchover of circuits under normal conditions.

Normal Operation Conditions:
1.ambient air temperature:ranged from -5°c~40°c,not exceeding 35°c averagely in 24hours.

2.location:Installation location can not exceed 2000 meters above sea level.

3.air condition:relative humidity in the installation place can not exceed 50% when the air reaches the highest temperature40°c,the average minimum temperature when it is the wettest can noe exceed 25°c

,relative humidity not exceeding 90%

4.Installation classification:grade2,grade 3

5.Installation pollution grade:grade 2

6.Installation type:din rail mounting

7:Installation conditions:magnetic field outside the installation place can not exceed 5 times of the site of terrstrial magnetism in all direction ,normaly speaking.RCCB should be mounted verically.if the operation handle puts through power sourse upward,there should be no notable compact and vibration in the installation place

Structure and Operation Principle

1)Structure

  Type F360 residual current circuit breaker consists of zero phase sequence current transformer,electromagnetic release,operation duvice,contactor system,arc-extinguishing device,insulation shell etc

2)Operation principle

 when the circuit works normally,residual current operation circuit breaker is in "on " position,when leakage or electric shock hazard occurs in the circuit ,the current transformer puts out a singal to make electromagnetic releade work,and cut off power source with in 0.1 second to prevent leakage
