Selection Notes
The fixed, rear-horizontal-terminal body and its 425 W power loss - well below the WMP equivalent's 743 W - suit a switchboard built for direct busbar entry rather than a withdrawable arrangement. With the LI release the breaker trips instantaneously on a short circuit, so it fits a sub-main or final position better than a main incomer that must stay closed through a downstream fault; the LSI-equipped 1SDA071792R1 in the same F HR body covers that case. At 100 kA Icu and a switched neutral, it is sized for the largest boards in the Emax 2 range.
