Selection Notes
Four poles put this 630 A Ekip Dip LSI breaker in installations where the neutral needs switching alongside the three phases, and the F F designation means it bolts in fixed with front terminals rather than racking into a cradle. The short-time delay stage inherent to LSI, with 42 kA Icw for 1 s, allows selective coordination with a downstream breaker instead of tripping instantaneously on every fault. At 31 W, power loss matches the three-pole F F version at the same current. The WMP moving part at the same 630 A, four-pole configuration is the withdrawable alternative.
