ABB UA30-30-10RA 230-240V 50Hz / 240-260V 60Hz 3 Pole Contactor

The ABB UA30-30-10RA Contactor (1SBL281024R8810, EAN 3471522302885) is a high-performance 3-pole capacitor switching contactor engineered for reliability in demanding power factor correction systems. Designed for both 50 Hz (230–240 V) and 60 Hz (240–260 V) applications, it ensures safe and efficient capacitor bank switching, even where peak currents can exceed 100 times the nominal RMS current. With integrated damping resistors, the UA30-30-10RA eliminates the need for additional inductances and minimizes inrush currents, protecting both the capacitor bank and the connected system. Built to IEC/EN 60947 standards, it offers long electrical durability, precise switching capability, and compatibility with a wide range of accessories, making it a trusted choice for industrial and commercial installations across India.
