## 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 16X12X6 enclosure.  Use in smaller enclosures is subject to end use evaluation.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
