The InN=50% marking on the type string indicates the neutral pole is rated at 50% of the phase current, which is standard for distribution MCCBs where the neutral carries only unbalanced load current, not full phase current.","metaTitle":"ABB 1SDA068106R1 XT4N MCCB, 250 A, 690 V, 4-Pole","metaDescription":"ABB 1SDA068106R1 XT4N 250 TMA MCCB, 250 A, 690 V, 4-pole, active production.
