Overview
Rockwell Automation has developed
global SCCR Selection Tables for
Component Drive circuits based on
common global motor voltages
(50/60 Hz) and short circuit current
rating fault levels. These tables allow
users the capability to select drive
circuit components over a wide
range of HP or kW ratings based
on common voltage and SCCR
application requirements.
Simply select the proper application
parameters as prompted by the
RockwellAutomation.com web tool
to locate the correct SCCR Selection
Table, then read the One-Line Bill of
Material for the desired motor rating.
Both component selection and short
circuit coordination is complete.
The selection tables are based on
compliance to IEC and UL standards,
and are in most cases covered by
third party witness by Underwriters
Laboratories and conducted in
Rockwell Automation accredited
test facilities.
