    I have a ABB Vacuum circuit breaker RMU IEC 60298, so its trip when load exceeds to set limit. Then I don't know how to set the trip setting of VCB or how to increase of load current setting of VCB?

    You will need to have a Short Circuit Corrdination Study performed by a qualified engineer for the system and/or circuit.

    Once this is done, the report will list the settings for this and any other distribution breakers.

    Any other method would be a guess, and if not guessed correctly, can be a serious hazard to the equipment, load, and personnel involved.
