Selection Notes
This 1250 A, 4-pole moving part pairs the LSI release's short-time delay with a fully-rated neutral, so it can both grade selectivity at 42 kA for 1 s and switch the neutral conductor on a four-wire system. It ships as the drawout part for a withdrawable cradle, in contrast to the fixed, front-terminal version of the same rating. Where the panel has no room for a withdrawable cradle, the fixed 1250 A, 4-pole breaker is the simpler choice.
