UA50-30-00RA 110V 50Hz / 110-120V 60Hz

Key Features

• 1
  1. High-Performance Capacitor SwitchingThe ABB UA50-30-00RA is specifically designed for capacitor switching applications, ensuring reliable and efficient operation in high-performance environments.
• 2
  2. Damping Resistors IncludedThe contactor comes complete with damping resistors, which limit the current peak on energization of the capacitor bank, ensuring safe and controlled switching.
• 3
  3. Capacitor PrechargingThe special front-mounted block ensures capacitor precharging, limiting the second current peak occurring upon making of the main poles, thereby preventing damage to the capacitor.
• 4
  4. Electrical DurabilityThe contactor has an electrical durability of 250,000 operating cycles for voltages below 500V and 100,000 cycles for voltages between 500V and 690V, making it a reliable choice for long-term use.
