SQD PL Breaker AIR rating
SQD PL Breaker AIR rating
(OP)
A SQD PL breaker has what appears to be 2 AIR ratings: one is 100kA (1ph) the other 14kA (3ph) at 480V. See pic. However, the SQD literature only has 100kA listed for this breaker.
Has anyone seen this type rating before? And 14kA seems awful low compared to 100kA rating.

For 3-phase application max fault current is 100 kA at 240 V and 14 kA at 480 V.

Ratings on the breaker take precedent over catalogue information.
