AQ-C255C Capacitor bank protection device AQ-C255C Capacitor bank protection device Ask for an offer Home Protection relays Capacitor bank protection AQ-C255C Capacitor bank protection device Description The AQ-C255C capacitor bank protection device has been specifically designed for the protection of capacitor banks. It includes voltage protections in addition to the new power factor controller that functions as the control unit of an automatic capacitor bank system and can control up to five (5) capacitor banks. AQ-C255C offers a modular protection and control solution for applications that require a large I/O capacity. You can add up to eleven (11) I/O or communication modules into the device for extensive monitoring and control applications. The AQ-C255C capacitor bank protection device communicates using various protocols, including the IEC 61850 substation communication standard. Highlights: A large I/O capacity. Voltage-based protections. Power factor controller for up to five (5) capacitor banks. A controllable color mimic with active feedback. Power and energy measurement accuracy of up to 0.2 %.
