Application
The UA.. contactors have been specially developed for the switching of capacitor banks whose inrush current peaks are less than or equal to
100 times nominal rms current. The table below gives the permissible powers according to operational voltage and temperature close to the
contactor. It also specifies the maximum peak current Î values accepted by the contactor.
The kvar ratings acc. to the table below are applicable to "star" connected capacitors (less current, cable savings).
The capacitors must be discharged (maximum residual voltage at terminals < 50 V) before being re-energized when the contactors are making.
In these conditions, electrical durability of contactors is equal to 100 000 operating cycles.
Selection Table
(
For 220 V and 380 V, multiply by 0.9 the rated values at 230 V and 400 V respectively.
Example: 50 kvar/400 V corresponding to 0.9 x 50 = 45 kvar/380 V.
If, in an application, the current peak is greater than the maximum peak current Î specified in the table above, select a higher rating, refer to the
UA...-R contactors (+ page 2/40) or add inductances (+ Application Guide "Contactors for Capacitor Switching").
The capacitor bank will be protected by gG type fuses whose rating is equal to 1.5 ... 1.8 times nominal current.
