Short Circuit Current Ratings (SCCR)

•

The suitable 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 Specifications” noted are suitable for achieving a SCCR of

10,000A (the default rating of terminal blocks).

•

Enclosure size – Investigated with a minimum 10X8X4 enclosure. Use in smaller enclosures is subject to end use

evaluation.
