Why Choose This Product
UA..RA contactors insert three damping resistors ahead of the main poles to pre-charge capacitors and tame the inrush peak at energization. That means cleaner switching, fewer nuisance trips, and longer life for your PFC components. If you’re building or maintaining capacitor banks and want dependable performance from a compact ABB unit, UA16-30-10RA is a smart, hassle-free pick.
Ideal For
-
Power factor correction (PFC) panels and capacitor bank switching
-
Industrial distribution boards and MCCs
-
HVAC plants, compressors, and chiller systems with PFC stages
-
OEM panel builders seeking IEC-compliant AC-6b performance
-
Retrofit projects where space and reliability matter
