1 Breaking time: The time interval between the switch dis-connector being powered from the shunt coil to the main circuit being disconnected at room temperature
2 Closing time: The time interval from the moment the switch dis-conenctor is closed to the moment when all contacts of the poles are in contact at room temperature. It is recommended to start measuring after the system stabilizes (200ms)
