The 'L-IR' designation indicates the long-time and instantaneous protection functions are adjustable, giving you coordination flexibility on a feeder or large motor branch circuit. The current-limiting action reduces let-through energy during a fault, which helps maintain selectivity downstream and limits thermal stress on buswork and cables. The lifecycle stage for this order code is listed as current, meaning it remains in ABB's active product portfolio. The current-limiting (C.LIMIT) designation means the breaker interrupts a fault before the first peak of the short-circuit current, which is what limits the mechanical and thermal stress on downstream components. This matters when you are coordinating a panel with multiple feeders: a current-limiting breaker at the main lets you use lower-rated branch devices without worrying about cascading failure.","metaTitle":"ABB XT4LU3225AFF00NXXX Circuit Breaker, 225A, Current Limiti","metaDescription":"ABB XT4LU3225AFF00NXXX circuit breaker, 225A current limiting L-IR, XT4 frame with rotary mechanism.
