ABB Capacitor Relay 50kVar 230VAC UA75-30-00-RA 25319. The capacitor relay can be used in installations where the peak current exceeds 100 times the rated rms current.
The contacts are delivered complete with damping resistors and should be used without additional inductances.
The capacitors must be discharged (maximum residual voltage at the terminals ≤ 50 V) before being reactivated during the contact construction.
The electrical endurance is 250,000 operating cycles for Ue 100 A at 440 V 1300 A. cos phi=0.45 (cos phi=0.35 for Ie > 100 A) at 690 V 630 A.
Operating Time: Between deactivation of the coil and opening of the NO contact 4 ... 11 ms. Between activation of the coil and closing of the NO contact 8 ... 27 ms.
