ABB XT5LU360BBFF000XXX XT5L 600 Breaking Part 3P F F, UL/CSA

The XT5LU360BBFF000XXX: This is the breaking mechanism only — the interrupting section of an XT5L 600 molded-case switch. It mounts into the XT5L 600 frame assembly; the '3P F F' designation means three poles with front-front terminal connections, typical for panelboard or switchboard lineups where bus connections enter and exit from the same face. The UL/CSA+TU suffix confirms it carries UL 489, CSA C22.2, and TU (likely Turkish Standards) certifications, so it's accepted in North American and Turkish distribution panels without additional testing.
