RCCB

Residual Circuit Current Breaker — disconnects in a fraction of a second when earth leakage is detected.

RCCB - Residual Circuit Current Breaker is an electrical wiring device whose function is to disconnect the circuit when it detects currents leaking to the earth wire. It also gives protection against electric shock or electrocution caused by direct contacts. RCCB is particularly useful in situations where there is a sudden earth fault occurring in the circuit, e.g. a person accidentally comes in contact with an open live wire in the circuit. In such situation, in absence of an RCCB in the circuit, an earth fault may occur and the person is at the risk of receiving an electrical shock. However, if the same circuit is protected with RCCB, it will trip the circuit in a fraction of a second thus preventing the person from receiving an electrical shock.

Therefore, it is a good and safe practice to install RCCB in your electrical circuit. A person can feel prickling sensations when he contacts with 10 mA of current. If he gets contact with 30 mA of current, he will face muscle contraction that might lead to respiratory paralysis. And when he gets in touch with above 100 mA, it will lead to electrocution.

Highlights

Technical ratings and application.

  • 01
    Rated residual current AnRated residual current An is the value of residual current specified by the manufacturer at which the residual current circuit breaker must switch out under specified conditions. Alternating residual current must release the residual current circuit breaker within An.
  • 02
    Rated current InRated current In is the value of current specified by the manufacturer, which can be transferred by the residual current circuit breaker continuously. So, the current In can pass through the contacts for an unlimited time.
  • 03
    Rated operating voltage UnRated operating voltage Un is the voltage the residual current circuit breaker is to be connected to and which properties are related to. The connected voltage has no effect on the device function but on the function of the test circuit and isolation properties.
  • 04
    Rated frequency fnRated frequency fn is the frequency the residual current circuit breaker is designed for and at which it works correctly under stated conditions. Majority of residual current circuit breakers are designed for fn=50 to 60 Hz. As the residual current circuit breaker function is based on the induction principle, the residual current behaviour and frequency show an effect upon tripping. When using a device designed for 50/60 Hz in a network with a different frequency, the user must count on a change of the tripping threshold.
  • 05
    Ambient temperature TAmbient temperature T for the residual current circuit breakers is (-5 to +40) °C according to almost all international standards. Some residual current circuit breakers work in an extended range (-25 to +40) °C.
  • 06
    Residual current circuit breaker - type ACResidual current circuit breaker - type AC - reacts to sine-wave residual current - it is used in conventional AC networks.
  • 07
    ApplicationProtection against indirect contact (indirect personnel protection). Protection is provided by disconnecting hazardous high touch voltages caused by a short circuit to exposed conductive parts of equipment.
