AL400L61K3 is a PowerPact Multistandard mechanical lug for PowerPact H, J, L-Frame breakers, these mechanical lug are made of aluminium. These lugs have a current rating of 250A and come in set of 3. Certified to UL & CSA Standards. The current-limiting attributes of PowerPact H-, J-, and L-frame circuit breakers provide greater protection for downstream devices by limiting the let-through current in the event of a fault. The current-limiting capabilities of HJ/HL/HR, JJ/JL/JR, and LJ/LL/LR frame circuit breakers are documented with Underwriters Laboratories and Canadian Standards Association. These current limiting circuit breakers ship with a label that identifies them as UL/CSA Current-Limiting Circuit Breakers.
