It's the configuration you'd reach for on a 208/240 V split-phase feed or a 480 V two-pole branch circuit where the neutral is solidly bonded and doesn't need switching. The XT4 frame is a standard panel-mount footprint — same cutout and bus-bar spacing as the rest of the XT4 family, so no rework if you're swapping in from a different rating within the series.","metaTitle":"ABB XT4NU3100FFF000XXX XT4N 250 EKI, 2-Pole","metaDescription":"ABB XT4NU3100FFF000XXX XT4N 250 EKI circuit breaker, 2 poles, current lifecycle stage.
