ABB Power Relay for Capacitors 15kVar 380VAC UA26-30-10-RA 25309

• Not suitable for installations with inrush current exceeding 100 times the nominal rms current.
• The contacts include suppression resistors and must be used without additional inductances.
• Pre-recharge of capacitors: maximum residual voltage across terminals ≤ 50 V before re-energizing.
• The electrical endurance is 250,000 operation cycles for Ue 100A at 440V, 420A with cos phi = 0.45 (cos phi = 0.35 for Ie > 100A) at 690V, 170A.
• Operation Time: Between coil deactivation and contact opening NO 4 ... 11 ms, between coil activation and NO contact closing 8 ... 21 ms.
