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
Main technical parameters:
