Residual current protection of the distribution box

Home / Residual current protection of the distribution box

Residual current protection can detect and isolate the grounding (leakage) fault of low-voltage distribution networks in time, which is an essential technical measure to reduce electric shocks and fire accidents and improve power supply safety. A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI)is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral. An RCD, which stands for Residual Current Device, is also known as a Residual Current Breaker (RCB) or Residual Current Circuit Breaker (RCCB). It is a safety device designed to protect against electric shock and hazardous fires.

Distribution systems and protection against indirect contact and earth

As previously explained, in TN distribution systems the earth fault currents result to be quite higher due to the low impedance value of the fault loop; as a consequence, in the most cases, protection against

How to Install and Test an RCCB

Proper installation and regular testing of Residual Current Circuit Breakers or RCCBs are essential to ensure they function as intended. Otherwise, they won''t provide a

Layout 1

Residual current devices with a tripping current of 30mA or less are now widely used in all types of electrical installation and provide valuable additional protection against the risk of electrocution.

Residual Current Protective Devices

As can be seen from the tripping curves, residual current protective devices do not limit the intensity of the residual current but provide protection due to fast disconnection of the power and therefore a

RD3 and RCQ020

Due to the wide current adjustment range (from 30mA to 30A) and to the large number of toroids available (openable and closed for cables or busbars), RD3 and RCQ020 residual current devices
