1200 A — what it means on the line
The ABB XT7SU312EPYW000XXR is a 1200 A molded case breaker from the XT7S series, 3-pole, rated 600 VAC. The 1200 A continuous rating governs the feeder or main disconnect it can protect — sized for a large motor control center, a transformer secondary, or a high-current distribution bus.
The line-side connector kit (included per the description) accepts Cu/Al conductors, simplifying bus-bar or cable landing.
