1. Introduction
Standard Arc Configurations (SACs) are fully tested and
documented preconfigured arc protection solutions. The
SACs approach save engineering time even in the most
complex applications and secure effective commissioning of
the EAFR-100 arc protection system.
To apply the SACs, the wiring and dipswitch settings of the
applied configuration shall be implemented as described
in the following sections. The amount of outgoing feeders
does not impact the settings, but only the quantity of the
units applied. The amount of arc sensors per zone may vary
and does not impact the settings. Therefore, the configura-
tions may be extended or reduced by adding or removing
units with identical settings and wiring. A different amount
or type of arc sensors per zone may be utilized as well.
Also, the protected zones may be reduced by simply not
connecting the sensors and/or trip signals of the respective
protected zone(s). In all configurations, there are a set of
user-selectable parameters such as current measurement
nominal values, enable/disable the CBFP function, and
choose the trip criteria (i.e.: trip on arc light only or simulta-
neous arc light and over-current condition).
The EAFR-110 series is applicable for other types of configu-
rations as well. If your particular application is not included
in SACs library, consult your nearest Eaton representative
for a solution.
