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 Specications” 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.
