The LSI trip curve means it provides long-time (L), short-time (S), and instantaneous (I) protection — covering overload and short-circuit fault clearing for high-current distribution. This is a current-production part per the lifecycle stage listing. The 6300 A continuous rating at the frame size means this breaker is sized for main incoming feeders or large busbar ties in industrial switchgear, not for branch circuits. The PR122/P-LSI trip unit allows field-adjustable protection settings via the front interface. The fixed version (no draw-out cradle) bolts directly into the switchgear cubicle — factor that into panel layout if future removal for test or swap is needed.","metaTitle":"ABB 1SDA057028R1 E6H 6300 PR122/P-LSI, 6300A 3P","metaDescription":"ABB E6H 6300 PR122/P-LSI IN6300A 3P W.
