The time current curves in this report represent the trip unit curves as provided by GE. Assessment of discrimination performance using these time current curves should take into account tolerance and a separation factor deemed acceptable by the customer. The curves do not take into account temperature deratings and should be considered cold curves (no preheating from previous starting currents/overloads etc).
Figures provided include Backup and Selectivity/Discrimination limits as per AS/NZS 3000 and AS/NZS 60947-2 they are supplied from GE published catalogues and take into account the selectivity/discrimination limits published by GE. Please refer to GE for any additional information. Example, Where 10/30 (discrimination/Backup kA) value means Selectivity is full up to 10kA and provide a backup protection up to 30kA
