Can the contact points of the intermediate relay operate properly at 660V?
Thread Content
During the work to modify the 660V control cabinet, it was found that the coil of the AC contactor operates at 660V. It is intended to add buttons for local start-up and to enable remote start/stop via an intermediate relay. I would like to ask: can the buttons be connected directly to the 660V coil of the contactor? Can the contacts of the intermediate relay handle 660V? What potential risks are there?
Check the label specifically; if connected to a high voltage, it may burn out due to overcurrent
