Short Circuit Current Ratings (SCCR)
• The suitable copper conductor ranges are limited to the table values only for achieving the SCCR in excess of the default
rating of 10,000A.
• Other conductor combinations within the “Terminal Specications” noted are suitable for achieving a SCCR of
10,000A (the default rating of terminal blocks).
• Enclosure size – Investigated with a minimum 16x12x6 enclosure. Use in smaller enclosures is subject to end use
evaluation.
