Product Description

Use in domestic, commercial and industrial installations. Principle of operation In the event of a short to earth the residual current operating system to prevent shock hazard voltage from remaining on the body of an electrical equipment. For this purpose, the residual current device monitor the difference between the loads flowing through it and ensures that it is aproximately zero. If, as a result of an earth fault, this difference exceeds the circuit breaker's residual operating current rating ln, then the RCCB will trip and disconnect the circuit of faulty equipment. (refer to Chart 1) Additional protection in the event of direct contact In order to provide additional protection in the event of a direct contact with (unearthed) live components, extremely sensitive RCCBs with a rated residual operating current of *0mA or less are used in place of more conventional RCCBs with higher residual operating current ratings.
