1. Application |
|
1).Protection against the effects of earth leakage overload and short circuit currents.
2).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.
3).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 |
