Technical parameters in practice

The device has a rated switching power Pe of 20 kW at 400 V and 10 kW at 690 V (in AC-3 category). The rated switching current Ie is 38 A (400 V) and 11 A (690 V) in the AC-3 category, respectively. The short-circuit current Icw(1s) is 1.2 kA, and the permissible short-circuit current Icm is 2.2 kA – these parameters demonstrate the high resistance of the device to overloads and short circuits. The rated insulation voltage Ui is 690 V, and the impulse withstand voltage Uimp is 6 kV – ensuring safety even in high-voltage installations. Mechanical durability at 3 million switching cycles guarantees long-term use without frequent device replacement.
