• Upon pressing the push-button "GCB OFF" or [GCP-32] "MCB ON" (depending on the breaker logic which
has been configured) in operation mode LOAD TEST
• In the event of an automatic stopping in the operation mode AUTOMATIC
• [GCP-32] following the "CLOSED TRANSIT." (
make-before-break/overlap synchronization) of the MCB
• [GCP-32] before the MCB is closed to the dead busbar in the case of the breaker logic "OPEN TRANSIT."
(break-before-make/changeover)
