Arcteq AQ-R215 -Railway Protection Device

 Description:

AQ-R215 Railway protection device is a three-phase feeder protection device that can be run either in Standard feeder mode or in Railway mode. In the Railway mode the device provides a single-phase overcurrent, earth fault, and voltage protection. Each protection stage can be independently set to the frequency of 16.67 Hz or of 50/60 Hz. When in the Standard mode the functionality of AQ-R215 is identical to that of the AQ-F215 feeder protection device. In this mode the relay can also be dynamically set to run on a frequency between 6 and 75 Hz.

You can add up to three (3) I/O or communication cards into the device for more demanding control, alarm and indication needs. AQ-R215 Railway protection device communicates using various protocols, including the IEC 61850 substation communication standard.
