The ABB XT3NU3080AFF000XXX is a 3-pole molded case circuit breaker from the XT3N 225 TMF 80-800 platform, rated 30 A continuous. That 30 A rating is the thermal-magnetic fixed trip — it governs the conductor and load sizing downstream. The 3-pole, 3-phase configuration means it switches all three phases simultaneously, which is standard for three-phase motor, feeder, or distribution circuits in a panel. The XT3N 225 frame carries up to 225 A in higher-rated variants, so this 30 A unit is a low-end tap off that same mechanical platform — same footprint, same accessory compatibility, just a lower trip coil.
Carries UL and CSA certification per the description. That means it is accepted for US and Canadian panel builds without additional agency review — a common requirement for North American industrial and commercial installations. RoHS and REACH compliance documentation is standard with ABB's XT series; the manufacturer provides declaration of conformity on request.
