The ABB UA75-30-10RA is a high-performance contactor specially developed for switching capacitor banks. It includes factory-mounted damping resistors that minimize the high inrush currents typically associated with capacitive loads. This ensures long-term reliability and prevents contact damage—making it ideal for power factor correction (PFC) systems.
Specialized for Capacitor Switching (AC-6b duty): Ideal for switching single or multiple capacitor steps in power factor correction equipment.
Built-in Damping Resistors: Significantly reduce high transient inrush currents, protecting both contactor and capacitor.
High Current Capacity: Rated up to 75 A for capacitor switching, ensuring robust operation in demanding environments.
3 Main Poles + 1 NO Auxiliary Contact (30-30-10 configuration): Facilitates control and monitoring functions.
AC Control Circuit Coil: Available in a variety of AC voltages to suit most industrial control systems.
Flexible Mounting Options: Suitable for DIN rail or panel mounting.
Extended Electrical & Mechanical Life: Engineered for durability in frequent switching applications.
Compact and Reliable Design: Saves space while delivering dependable performance.
Complies with IEC/EN 60947-4-1 Standards: Ensures global acceptance and compatibility.
