Protection against the effects of earth leakage overload and short circuit currents.
2P switching of ph&N,Phase only protected against overloads and short circuits.
In commercial,industrial and domestic electrical distribution systems.
Note: must mot be used as the sole means of providing protection against direct contact.
The RCBO incorporates a residual current operated electromagnetic release which operates without any auxiliary source of suppl to open a circuit automatically in the case of an earth leakage fault between phase and earth greater than or equal to In.
The RCBO combined MCB & RCCB provides: Protection against indirect contact, Complementary protection against direct contact, Protection for the installation against in sulation faults
Standard: GB16917.1, IEC61008
