You said that "it takes 10 minutes to close the brake when it trips regularly every day", which means that it is not the leakage protection trip, but the overcurrent protection trip, because the switch overcurrent protection is thermal protection, and it is necessary to wait until the temperature of the protection device drops before closing the brake after tripping. That is to say, the switch has overcurrent, and the load is the largest at this time of the day, which exceeds the rated current of the switch overcurrent protection. Please check the set current of the switch overcurrent protection (the rated current of the switch is adjustable between 200 and 400 A). ), and then measure the three-phase current at this time of tripping every day to see if it exceeds the rated current.
