AQ-F213B Feeder Protection IED

The AQ-F213 IED provides optimal performance for main medium voltage or back-up high voltage protection, control and monitoring applications. The AQ-F213 integrates protection, control, monitoring, measuring, communication and extensive diagnostics information in one compact package. Fully modular hardware construction gives a high level of flexibility; additional I/0 or communication cards can be simply plugged in according to application needs.

The AQ-F213 is developed using the latest available technologies providing a totally new dimension and options to protection engineers. Maximum usability of the IED is guaranteed by features such as graphical interfaces, highly customizable HMI, storage of pdf or other supportive documents and extensive user log informati­on. Easy to use and powerful conguration and setting software tools are provided free of charge.
