UA50-30-00RA 220-230V 50Hz / 230-240V 60Hz

Key Features

• 1
  1. High Inrush Current HandlingThe ABB UA50-30-00RA is designed to handle peak currents far exceeding 100 times the nominal RMS current, making it suitable for high-capacity capacitor banks.
• 2
  2. Block-Type DesignThe contactor features a block-type design, which ensures the serial insertion of 3 damping resistors into the circuit to limit current peaks during capacitor bank energization.
• 3
  3. Damping Resistors IncludedThe contactors are delivered complete with their damping resistors, eliminating the need for additional inductances and ensuring safe operation.
• 4
  4. Capacitor PrechargingThe contactor's design ensures capacitor precharging, which limits the second current peak occurring upon making of the main poles, enhancing overall system stability.
