Three poles make it suitable for three-phase feeder or motor branch circuits in a distribution panel. ## Compliance and certification coverage The description carries UL and CSA marks, so the breaker is accepted for North American panel builds without a separate evaluation. For an OEM purchasing agent or independent trader, this means the documentation package (UL file, CSA certificate) is standard with the part — no special compliance project needed to use it in a UL 508A or CSA C22.2 No. 5 application.","metaTitle":"ABB XT4NU3150B6600HXXX MCCB, 3-Pole, 150 A, TMA Trip","metaDescription":"ABB XT4NU3150B6600HXXX 3-pole MCCB with TMA 150 A trip unit, 750-1500 A short-circuit range.
