It is a 3-pole unit with F F designation, certified to UL/CSA and TU standards. This is the interrupting section of the breaker assembly — the part that carries the arc chambers, contacts, and trip mechanism — designed for integration into the XT5L frame. Typical applications include main or feeder protection in industrial distribution panels, motor control centers, and switchgear rated for 600A continuous current. The 600A frame rating sets the maximum continuous current this breaking part can carry without derating. For a panel OEM or MRO planner, that means sizing the upstream bus and downstream conductors for 600A at the rated ambient. The 3-pole configuration covers three-phase systems; the F F designation indicates fixed thermal and fixed magnetic trip settings — no field-adjustable trip unit. That simplifies ordering (one part number, no trip-setting ambiguity) but locks the protection curve to the factory calibration. For a commissioning engineer, verify that the fixed trip matches the load's inrush and fault-clearing requirements before the breaker goes into the switchboard. ## Mounting and integration note This is the breaking part only — it installs into the XT5L molded case frame. For a panel wireman or field service tech: the breaking part slides into the frame and locks with the integral latch; no separate mounting hardware is needed. The line and load connections are on the frame, not the breaking part. When replacing a failed breaking part, isolate the frame, discharge any stored energy in the system, and verify the frame model matches XT5L before inserting the new unit. The UL/CSA+TU listing covers the assembled breaker, so using this breaking part in the correct frame maintains the certification.","metaTitle":"ABB XT5LU360BFFF000XXX MCCB, 600A Breaking Part, 3-Pole","metaDescription":"ABB XT5L series 600A breaking part, 3-pole, UL/CSA+TU.
