Contact Output Example for Overcurrent Warning
The 07-08 auxiliary contact can be used for overcurrent warning, dedicated ground fault or dedicated instantaneous according to
settings. Activating the instantaneous function (Sc) forces the contact to be set for instantaneous. When current flow exceeds overcurrent
warning threshold parameters, the warning terminal opens and closes repeatedly every second. When the trip occurs, the alert contact
output would be identical to the trip contact (a).
Example when using the Dedicated Ground Fault/Instantaneous Contact
When using the dedicated ground fault/instantaneous contact, the main contacts (95-96, 97-98) will not activate under ground fault/
instantaneous conditions. When the dedicated ground fault contact function is not used, the main terminals (95-96, 97-98) activate
identically to normal trip conditions when a ground fault/instantaneous occurs. When the instantaneous setting is activated, the
auxiliary terminal (07-08) is automatically set to instantaneous contact, and can no longer be used as overcurrent warning or ground
fault contact.
