Description
The AQ-F255 feeder and line protection devices offer a modular protection and control solution for 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. The AQ-F255 feeder and line protection devices 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, B, C, R, S, and V. See below for their individual differences.
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).
