Marathon offers 600 Volt Power Distribution
Blocks with high SCCR’s in response to new
2005 NEC® and UL508A marking requirements
With High Short-Circuit Current Ratings
The requirements of the 2005 National Electric Code (NEC) and UL508A now require many
electrical panels to carry a Short Circuit Current Rating (SCCR). Analyzing the SCCR of
individual components and overcurrent protection devices is a method of determining the
SCCR of an electrical assembly.
Marathon’s Power Distribution Blocks are standard products that have been used in
electrical control panels for over 35 years. These blocks have now been tested and
approved for higher SCCR. The higher ratings are based on proper wire sizes and the
appropriate circuit protection device. UL508A does allow default SCCR for Power
Distribution Blocks of 10,000A with no additional testing.
Marathon’s Power Distribution Blocks (UL File # E62806) are recognized under UL
Standard 1059 and have been investigated by UL for Short-Circuit Current Ratings (SCCR)
as described in the UL Guide Information for category XCFR2; Terminal Blocks-Component.
Marathon's new Power Distribution Blocks (UL File # E309401) are listed to UL 1953. The
feeder spacing requirements of UL508A are achieved with these blocks.
For rating details see detailed data sheets at www.marathonsp.com. These data sheets contain
valuable product information including a photo of the product, technical drawings, short circuit current
ratings, electrical and mechanical ratings and agency approvals.
