FAQ
-
1.What should be done if the contactor gets "stuck" and the current cannot be cut off?
This is a common safety hazard existing in the high current test. To address this, the equipment adopts a dual physical disconnection protection mechanism: in addition to the main contactor, an emergency safety air switch or physical fuse device is also configured; in case of abnormal conditions, forced power-off can be achieved through the secondary circuit, effectively avoiding the risk of fire caused by continuous overheating. -
2.How does the equipment capture the instantaneous peak value of short-circuit current?

3.Can different voltages be tested?
