The ABB 1SAM201906R1115 is a 65 A busbar for circuit breaker distribution panels — a current-production accessory that ties multiple breaker poles to a common supply without additional wiring. Rated at 65 A, it handles the feed for a group of miniature or moulded-case breakers in a sub-distribution board, sized for typical commercial and light-industrial loads.
Mounts directly onto the breaker terminals in a DIN-rail enclosure; the 65 A rating matches the busbar's own cross-section, so no additional derating is needed when feeding breakers with a combined load up to that figure.
