Residual Current. The main application is to prevent electrocution but rcds can also be used to protect equipment especially against fire. Residual current circuit breaker rccb this device is essentially a mechanical switch with the residual current tripping characteristic attached to it.
So basically it will only break the circuit when there is a leakage current flowing to earth. The residual current device rcd is used to detect earth fault currents and to interrupt supply if an earth current flows. A residual current device rcd residual current circuit breaker rccb or ground fault circuit interrupter gfci is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.
A residual current device rcd residual current circuit breaker rccb or ground fault circuit interrupter gfci is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.
Rccb is designed such way that it continuously senses the residual current or the difference in current values between the live and neutral wires. A residual current device rcd residual current circuit breaker rccb or ground fault circuit interrupter gfci is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock. The tripping time is such as to minimise the risk to human life. Residual current devices rcd are designed to provide protection against hazardous earth fault current.
