Description
AQ-F255 Line and Feeder Protection Devices offer a modular protection and control solution for both line and feeder applications that require a large I/O capacity. Additionally, depending on the model the devices integrate various protection functions. You can add up to 11 I/O or communication modules into the device for extensive monitoring and control applications. AQ-F255 communicates using various communication protocols, including communication according to the IEC 61850 standard.
We offer six (6) variants of the AQ-F255 feeder protection device: A–C, R, S, and V. See below for their individual differences.
- AQ-F255A – full feeder functionality
- AQ-F255B – line differential protection + current protection
- AQ-F255C – line differential protection + full feeder functionality
- AQ-F255R – full feeder functionality + special object for phase-specific tripping and recloser control
- AQ-F255S – full feeder functionality + synchronizer
- AQ-F255V – full feeder functionality + AVR + transformer module
Highlights:
- A large I/O capacity.
- Current-based and voltage-based protection functions.
- Power and energy measurement accuracy with a precision error as low as 0.2 %.
- Line differential protection (transformer in protected zone).
- Low-voltage ride-through protection.
- IEC 62443-4-2 compliant cybersecurity (security level 1).
