The XT7SU312ETFF000XXX: Lifecycle stage is current, which means ABB continues to manufacture and support this order code. No phase-out or last-time-buy window has been announced. For BOM freeze or PCN watch purposes, this part is stable on the line card.
The XT7S frame mounts in standard switchgear or panelboard cutouts. The EKIP HI-TOUCH LSI trip unit provides adjustable long-time, short-time, and instantaneous protection — set via the front-panel interface without needing a separate programming tool. The FF UL suffix confirms UL 489 listing, so it is accepted for service entrance or feeder protection in US and Canadian installations.
