This is the FF variant, meaning fixed front terminals for panel wiring. The 800 A frame and EKIP DIP LS/I trip unit make this breaker suited for main feeder or large motor-circuit protection in industrial switchboards. The electronic trip unit gives adjustable long-time (L) and short-time (S) delay plus instantaneous (I) pickup, which allows selectivity coordination downstream — a key requirement for panel builders aiming to minimize nuisance tripping on fault clearance. The 3-pole FF terminal configuration is a standard fixed-connection pattern for panel-mounting; verify bus-bar or cable lug compatibility with the terminal pad dimensions before specifying. ## Deployment Context Mounts in a standard switchboard or panel enclosure on a mounting plate — the XT6N frame is a bolted, not DIN-rail, installation. The UL/CSA certification listed in the description means the breaker carries North American approvals for 600 VAC applications, so it is accepted in US and Canadian panels without additional agency review.","metaTitle":"ABB XT6NU3800EFF000XXX XT6N 800A 3P Molded Case Circuit Brea","metaDescription":"ABB XT6NU3800EFF000XXX molded case circuit breaker, 800A, 3-pole, EKIP DIP LS/I trip unit.
