WIDE ADJUSTMENT RANGE
EOCR has a wide current adjustment range of over
10:1. It enables three type models to cover a wide
range from 0.1A up to 600A thus reducing the
number and type of relays that must be inventoried
for spare purposes.
LOOPING OPTION
Some motor size may require only one-third or
one-fourth of particular EOCR current range. These
installations can be accommodated by looping
the motor wire 2 or 3 times through the integral
current transformers of the EOCR. This reduces
the number and type of relays inventoried for
spare purposes. Each additional loop will increase
the current measured as indicated by the following
chart.
