Acti9 CDS
  • Features

    With priority channels adjustable from 5 to 90 A and a helpful LED indicator to inform you when load shedding occurs, the Acti9 CDS load shedding contactor provides flexibility and enhances the continuity of supply.
    • CDS products avoid breaking of the main circuit breaker when power consumption exceeds the power subscribed by the consumer
    • As soon as the total current drawn exceeds the pre-set threshold, the contactor will temporarily break supply to the circuits considered to be non-priority
    • Priority channel adjustable from 5 to 90 A, non-priority channels 15 A
    • Voltage rating - single phase: 240 V A + 5 % - 10 %, 3-phase: 415 V AC + 5 % - 10 %
    • Frequency: 50 /60 Hz
    • LED to indicate installer when load shedding occurs
    • Restoration period: 5 to 10 mn
    • Option to override with a load shedding override input
    • 1 A rating NO contact allowing remote indication of load shedding or direct load shedding via a NC contactor.

    Suitable for residential and commercial buildings, the Acti9 CDS load shedding contactor provides a reduction in energy bills, enhanced continuity of supply and expert management of load shedding.
    • Reduces electricity bills through the reduction of subscribed demand
    • Increases the number of loads that can be managed, without increasing subscribed demand
    • Enhances continuity of supply: as soon as the power consumed by the installation approaches the power set on the product, Acti9 CDS shed non-priority loads in cascade.


    Specially designed for residential and commercial installations up to 36 kVA, the Acti9 CDS load shedding contactor is not only easy to install, but effectively reduces electricity bills whilst ensuring enhanced continuity of supply.
    • Reduction of electricity bills by authorizing reduction of subscribed demand
    • Installed in the electrical switchboard, the load shedding contactors are designed to be implemented by an electrical contractor.
