The 2005 National Electric Code (NEC) and UL 508A (effective
April 25, 2006) require many electrical panels to have shortcircuit current ratings (SCCRs). Rockwell Automation is a leader
in the industry for supplying a broad range of products with
high-fault SCCRs, including but not limited to: terminal blocks,
power blocks, circuit breakers, contactors, disconnects and drives.
These ratings allow terminal blocks and power distribution blocks
to be used in conjunction with fuses, motor protection circuit
breakers, and motor circuit protectors in power circuits. When
you use components with SCCRs rated jointly, the process of
obtaining SCCRs for UL 508A electrical panels may be simplified.
All terminal blocks were granted a default 10 kA SCCR
for use in power circuits (UL508A). The UL508A offers criteria
for determining panel SCCR based upon the component with
the lowest SCCR in the power circuit, creating a limitation 10 kA
for power circuits using untested terminal blocks. Many users that
comply with the UL508A standard are looking to achieve overall
system ratings between 25 kA and 100 kA.
To assist our customers and support UL requirements,
we offer several types of terminal blocks tested and certified
by UL with high-fault SCCRs. We also meet or exceed
requirements of CSA, IEC, NEMA and other international
standards. By meeting these requirements and with our global
capabilities, our products can be used in the US and incorporated
into equipment which will be exported around the world.
