AKBO1-63M Residual Current Breaker Overload
Overcurrent protection
Operates on thermal and magnetic tripping principles in the line side.Overload and short circuit protection meets requirements in IEC60898-1.
Earth leakage protection
Operates on detection of differential current between line and neutral currents.Electronic sensing initiates amplification in circuitry to provide high sensitivity.Crucial tripping time is wellbelow set standard which helps safeguard human lifes.
Operation of test button
The test buton(marked T)should be depressed momentarily in the activated circuit to check the integrity of the tripping mechanism and functions of the unitThe RCBO unit should be checked every quaterly using the test button.If it fails to trip,seek help from the electricians.
Note:Operation of the test device checks only the correct functioning of the RCBO at a higher cur- rent than the rated tripping level.It does not check the integrity of the earthing system.
Installation
■Plug in the RCBO unit with L(in)terminal onto the "Live"busbar of the consumer unit plug in board;
■Connect hte BLACK neutral [N(in)]to the neutral supply terminal block;
■The load connections are made to the outgoning terminals of the RCBO marked L(out)and N lout).N (out)must not be connected to the neutral supply terminal boock.The load cables must be of the correct size corresponding to the RCBO current ratings:
Upon activation of power after installation,depress"T"button to test unit.
Caution:High voltage insulation testers must not be used with the RCBO in circuit.
