Long Description

The ABB UA95-30-11-84 Capacitor Duty Contactor is engineered for switching three-phase capacitor banks in power factor correction applications. This model has a 110V AC control coil for 50Hz supplies and supports 110–120V AC at 60Hz, making it important to verify the control supply voltage before installation.

It includes three main normally open poles for switching the capacitor circuit and 1NO + 1NC auxiliary contacts for control and status signalling. Designed for capacitor switching, the UA95 series accommodates high inrush current, with a permissible peak current up to 30 times the nominal RMS current. Its AC-6b rating is 65 kVAr at 400/415V and 40°C.

With a conventional free-air thermal current of 145A at 40°C and cable-clamp terminals, this contactor is suitable for use in industrial APFC panels and capacitor-bank assemblies. Select the contactor according to the required coil voltage, capacitor-bank rating and system conditions.
