Single-pole means it switches one phase, so it's a fit for 120/240 V split-phase or single-phase line-to-neutral circuits where you don't need multi-pole coordination. Wall-mount form factor means it bolts directly to a backplate or enclosure wall — no DIN rail required. That's handy for retrofit work where the existing panel layout doesn't have rail space, or for standalone sub-panel protection near a motor or control transformer. The XT4N 250 TMF series uses a compact footprint; verify the drilling template against your gland plate before committing the panel layout.","metaTitle":"ABB XT4NU3100AFF000XXX XT4N 250 TMF, 20 A 1-Pole Wall-Mount","metaDescription":"ABB XT4NU3100AFF000XXX XT4N 250 TMF circuit breaker, 20 A, 1 pole, wall mount.
