Description

The ABB UA63-30-00RA AC Contactor offers precise capacitor switching for industrial and commercial PFC systems. Its integrated damping resistors reduce inrush and precharge capacitors before main contact engagement, protecting components from damaging peaks. The block-type design supports easy mounting and wiring. For comprehensive automation and integration solutions, visit our automation and system integration company Egypt.
