Load Shedding

Load shedding does not trip the circuit breaker, but may be used to activate an alarm linked to an M2C or M6C contact (controlling non-priority network loads).

• Load shedding is defined by a threshold and time delay:

  A—Activation threshold

  B—Activation time delay

  C—Dropout threshold

  D—Dropout time delay

• Power load shedding depends on the flow direction set during trip unit setup.

• Current load shedding is connected to the I²t or Idmtl long-time delay values.

• Current load shedding cannot be activated if “Long-time OFF” rating plug is installed.
