Selection Notes

Four poles put this 1250 A Ekip Dip LSI breaker in TN-S or TT installations where the neutral has to be switched along with the three phases, and its fixed, front-terminal (F F) build means it bolts straight to the busbar instead of racking in and out. The short-time delay inherent to the LSI release, combined with the 42 kA/1 s Icw rating, allows it to stay closed through a downstream fault long enough for a feeder breaker to clear first. Power dissipation at 122 W is roughly half that of the withdrawable (WMP) version at the same rating, a difference worth factoring into panel thermal design. For rack-in isolation, the WMP moving part at the same frame is the alternative.
