          Shed non-priority loads Automatically

           
           

          Main drivers

          I want to optimise my energy usage. I can shed non-critical loads to make sure I stay within my utility tariff, but I can’t afford sudden power cuts.

          Solution in brief

          Design your electrical system around Compact NSX circuit breakers


          Compact NSX circuit breakers allow you to manage reflex load shedding: the automatic shedding of specific loads.

           

          The Compact NSX circuit breaker with integrated Micrologic 5.2 E electronic trip unit sends the reflex load shedding command. The trip unit measures I, V, P and E, and produces the appropriate alarms. Each alarm is associated with a load shedding trigger setting and a deactivation setting, each with time delay. The reflex load shedding order is sent via the Compact NSX circuit breaker’s SDx output module.

            PT: Pick-up threshold
          PD: Pick-up time delay
          DT: Drop-out threshold
          DD: Drop-out time delay
          Alarm: activation zone (in blue)
          Each alarm is associated with a load-shedding trigger setting and a deactivation setting.
