Elpress AKK630A-1 — bimetallic (AlCu) compression cable lug for terminating a 630 mm² aluminium conductor (bolt-hole variant -1). The aluminium barrel is friction-welded to a copper palm from solid material, so an aluminium conductor can be connected directly to a copper busbar or apparatus without a separate bimetal washer. Accepts solid (IEC 60228 Class 1) and stranded (Class 2) aluminium conductors; two compression crimps are made on the aluminium barrel. Tested to IEC 61238-1 within the Elpress crimp system.
