50% of Nominal Current

This alarm indicates that the load current exceeded 50% of the nominal current or exceeded 50% of the associated circuit breaker rating (Ir). On polyphase circuits, the alarm triggers if the current of one of the phases meets the above conditions. The gateway manages the alarms based on the values of the currents sent by the wireless device. The response time of the alarm depends on the communication period set into the PowerTag system wireless network (default = 5 seconds). The alarm automatically disappears when the load current remains below the threshold value for 15 minutes.

NOTE: Hysteresis of 10% is applied on the threshold value.
