Show me the rating: 200 A continuous, with the L-IR trip providing adjustable long-time (L) and instantaneous (I) protection plus a fixed short-time (S) delay band for selective coordination downstream. The current-limiting action means the let-through energy (I²t) is held below the damaging threshold for downstream components during a short circuit, which is what allows series ratings and reduces required SCCR on the load-side gear. No ground-fault (G) element in this variant — if GFP is required, the order code needs the G suffix. ## Panel integration The rotary mechanism shaft extends through the door; the escutcheon plate and handle are ordered separately if the panel design needs them. Terminal spread is fixed — verify lug spacing against the existing busbar or cable set before committing the layout.","metaTitle":"ABB XT4LU3200AFF00NXXX XT4 Molded Case Circuit Breaker, 200A","metaDescription":"ABB XT4LU3200AFF00NXXX XT4 molded case circuit breaker, 200 A, current-limiting, L-IR trip unit, rotary mechanism.

The deciding factor is the panel-door interface: if the design requires a through-door rotary operator, this order code is the correct fit; if a standard toggle handle is acceptable, the non-rotary variant saves panel cutout complexity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/XT4LU3200AFF00NXXX","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/XT4LU3200AFF00NXXX when reusing this data.
