General

• This is B Type Residual Current Circuit Breaker

  • Tip: Please noted the input MUST from TOP side, or will damage the product.

  
  

  Type B RCCBs, in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents. Reducing the risk of fire and/or electrocution through automatic disconnection of the electrical supply relies on the selection of the correct type of RCCB.

  1.1 Function
•  Control electric circuits.
   Protect people against indirect contacts and additionalprotection against direct contacts.
   Protect installations against fire hazard due to insulation faults.Residual current circuit breakers are used in housing, tertiarysector and industry
• 1.2 Selection
   Detectable wave form
   B class
   Tripping is ensured for sinusoidal AC residual currents pulsed DCresidual currents,
  alternatingresidual sinusoidal currents up to1000Hz, pulsating direct residual 
  currents and for smooth directresidual currents, whether applied suddenly or increasing slowly.
   Tripping sensitivity
   30mA -additional protection against direct contact.
   Tripping time
    Instantaneous

    It ensures instantaneous tripping (without time- delay).
