YCB7RL-63 Residual Current Circuit Breaker


  • 1.Protection against the effects of sinusoidal alternating earth fault currents
    2.Protection against indirect contacts and additional protection against direc
    contacts
    3.Protection against fire hazard caused by insulation faults
    4.Controlling and Switching
    5.Used in residential building, non-residential building, energy sources, industr y
    and infrastructure

  • TypeTripping sensitivity data
    ACFor residual sinusoidal alternating
    currents
    30mAFor personnel, material and fire
    protection, as well as for protection
    against direct contact
    AFor residual sinusoidal alternating
    currents and residual pulsating
    direct currents
    100mAFor providing protection against
    indirect contacts
    SFor selectivity, with time delay300mAFor preventative fire protection in
    case of insulation faults
