The ABB UA110-30-00RA 110 V, 50 Hz capacitor duty contactor is intended for switching three-phase capacitor banks used in power factor correction installations. It can be integrated into suitable electrical panels to control capacitor-bank operation in commercial and industrial systems.

This model features a 110 V AC control coil at 50 Hz—rated 110–120 V at 60 Hz—and three normally open main contacts. Its rated capacitor-switching capacity is 80 kVAr at 400/415 V and 40°C, 70 kVAr at 55°C, and 60 kVAr at 70°C. ABB also specifies a permissible peak current of up to 100 times the nominal RMS current during capacitor switching. ABB eMart

Part of ABB’s capacitor duty contactor range, the UA110-30-00RA is suited to applications where its switching capacity, control supply and installation conditions match the system requirements. Before ordering or installation, confirm the capacitor-bank rating, coil voltage, ambient temperature, protection arrangement and panel compatibility.
