Description
The ABB UA75-30-00RA Contactor (Product ID: 1SBL411024R8000) is a high-performance 3-pole contactor specifically designed for capacitor switching applications. It is engineered to handle installations where the peak current can exceed 100 times the nominal RMS current, making it ideal for capacitor bank switching in industrial power systems.
This contactor comes complete with integrated damping resistors, ensuring controlled inrush current during capacitor energization. The special front-mounted resistor block provides serial insertion of three damping resistors to limit current peaks and precharge the capacitors, reducing electrical stress and extending system lifespan.
Designed for demanding environments, the UA75-30-00RA offers high electrical durability and reliable operation in power factor correction systems, industrial plants, and heavy-duty electrical installations.
