UA50-30-00RA 190V 50Hz / 220V 60Hz

Key Features

• 1
  1. High Current HandlingThe UA50-30-00RA is designed to handle peak currents far exceeding 100 times nominal RMS current, making it suitable for demanding applications.
• 2
  2. Damping Resistors IncludedThe contactor comes with built-in 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 extending the contactor's lifespan.
• 4
  4. Electrical DurabilityThe UA50-30-00RA has an electrical durability of 250,000 operating cycles for voltages under 500V and 100,000 cycles for voltages between 500V and 690V, ensuring reliable performance over time.
