FCL3-2, Earth Leakage Circuit Breaker

• Product Name:
  Earth Leakage Circuit Breaker
  
  
• Model Number:
  FCL3-2
  
  
• Description:
  Introduction:
  (F360) Residual Current Circuit Breaker without over current protection conforms to the standards of GB 16916.1, IEC1008, and BS4293 etc.
  It is used in the circuits of AC 50 ~ 60HZ, single phase 230V (220V), three phases 400V (380V) in industrial & mining enterprises, commercial buildings and housing for protection of personal electric equipment from electric shock hazard, and also can be used for infrequent switchover of circuits under normal conditions
  

  　 1. Ambient air temperature: ambient air temperature ranges form -5degree Centigrade~40degree Centigrade, not exceeding 35degree Centigrade averagely in 24 hours.
  　 2. Locations: Installation location can not exceed 2000 meters above sea level.
  　 3. Air conditions: Relative humidity in the installation place can not exceed 50% when the air reaches the highest temperature 40degree Centigrade, the average minimum temperature when it is the wettest can not exceed 25degree Centigrade. Relative humidity not exceeding 90%.
  　 4. Installation classification: Installation is divided into grade II. Grade III.
  　 5. Installation pollution grade: installation pollution grade is grade II.
  　 6.Installation conditions: magnetic field outside the installation place can not exceed5 times of the site of terrestrial magnetism in all direction Normally RCCB 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. vibration in the installation place.
  　 7. Connection it can be connected with screws or bus bar.
  
  Structure
  　　 FCL3 Residual current circuit Breaker consists of zero phase sequence current transformer. Electromagnetic release. operation device. contactor system arc-extinguishing device, insulation shell etc.
  　　 Operation principle
  　　 When the circuit works normally residual current operated circuit breaker is in "on" positing, When leakage or electric shock hazard occurs in the circuit the current transformer generates a signal to make electromagnetic release work and cut off power source with in 0.1 second to prevent leakage.
