LS Electric PB-3P18M80A-HUC Busbar – 3-Pole, 18-Pin, 18mm Pitch, 80A, UL 489 Rated, Cuttable

This busbar is specifically engineered for UL 489 applications, which are more stringent than the standard UL 1077 (supplementary) ratings. It is designed to fit LS Electric BKN-b and BK63H series breakers but is compatible with most 18mm-pitch UL 489 MCBs that accept spade/fork-style connections. The 18-pin configuration allows you to power six 3-pole breakers or eighteen single-pole breakers (staggered across phases) with a single line-side feed.
