The rotary handle extends through the door for a padlockable, externally operated disconnect — common on motor control centers and distribution panels where a visible break is required for lockout/tagout. The 80 A rating suits feeder circuits, branch protection for motor loads, or main disconnects in sub-distribution boards. ## What the L-IR trip unit means for coordination The L (thermal) element provides overload protection with a fixed time-current curve; the I (instantaneous) element clears short-circuits above a fixed threshold. Because it is current-limiting, the breaker limits peak let-through current and I²t energy, which simplifies selective coordination with downstream breakers — a useful property when designing a distribution panel where you want the branch breaker to trip before the main. The fixed settings mean no field adjustment; the trip curve is set at the factory per the 80 A rating.","metaTitle":"ABB XT2LU3080BFF00NXXX Molded Case Circuit Breaker, 80A","metaDescription":"ABB XT2LU3080BFF00NXXX molded case circuit breaker, 80A, current-limiting L-IR, rotary handle.
