The ABB UA16-30-10RA is a specially designed contactor for switching capacitor banks. It includes pre-installed damping resistors that limit inrush current and prevent contact welding—ensuring a longer service life and stable performance during capacitor switching operations.

✅ Key Features:

• Specialized for Capacitor Applications: Designed to switch capacitive loads efficiently and safely.

• Integrated Damping Resistors: Reduces high inrush currents, protecting both the contactor and the capacitors.

• Compact Design: Saves space in panels and improves layout flexibility.

• AC Control Circuit: Coil voltage suitable for common AC control applications.

• Rated Current: Up to 16 A for capacitor applications (AC-6b duty).

• 3-Pole Configuration + 1 NO Auxiliary Contact: Ensures reliable control and signaling.

• DIN Rail or Screw Mounting: Flexible installation options for control panels.

• Long Electrical Life: Enhanced durability under frequent switching conditions.

• Compliance & Certification: IEC/EN 60947-4-1 standards for low-voltage switchgear.
