For Tesys "D" Contactors - Can the rated operational AC voltage exceed 690 V or it is maximum 690 V ?
For the Tesys "D" Contactors,
The rated operational AC voltage is as follows:
1- 690 V AC up to DT80A ( 4 poles - 80 A on AC-1 Contactor)
2- 1000 V AC from D80 to D150.
So it can exceed the 690 V AC rated operational voltages but with the above mentioned range only (starting from D80).
