That 30 A figure is the thermal-magnetic fixed-trip rating — it governs the load it can carry without nuisance tripping and sets the upper bound for the branch circuit it protects. On a 3-phase motor or resistive load, this is the number you match to the nameplate FLA or the calculated load current; oversizing past 30 A means the switch won't clear a fault before the downstream equipment takes damage. ## Deployment context","metaTitle":"ABB XT4NU2175AFF000XXX XT4N 250 TMF, 30 A 3-Pole","metaDescription":"ABB XT4NU2175AFF000XXX XT4N 250 TMF molded case switch, 30 A, 3-pole, 3-phase.
