What this order code decodes to
The order code breaks down as XT6H frame, 800 A, EKIP DIP LSI electronic trip unit, fixed front terminals (FF), UL/CSA certified variant. The EKIP DIP LSI trip unit provides LSI protection — long-time, short-time, and instantaneous — with DIP-switch adjustable settings, giving the site electrical engineer selectivity headroom downstream of a transformer or upstream of a distribution panel.
The lifecycle stage for this order code is listed as current, meaning ABB has not issued a discontinuation notice or last-time-buy window for this variant. For a strategic sourcing lead managing a BOM freeze, this is the preferred status — no PCN-driven rush to qualify a replacement.
The FF (fixed front terminals) designation means the line and load connections are fixed terminals at the front of the breaker — no plug-in base or draw-out cradle. Panel integration is straightforward: mount the breaker on the DIN rail or panel plate, torque the terminals per the nameplate, and route the bus bars or cables. The 800 A frame typically requires bus-bar support brackets and a minimum clearance to adjacent devices for heat dissipation; per the XT6H family practice, side-by-side mounting without derating is allowed up to 70% of rated current, but for full 800 A continuous, a 25 mm air gap between breakers is standard.
What the EKIP DIP LSI trip unit means for coordination
The EKIP DIP LSI electronic trip unit gives the commissioning engineer field-adjustable long-time pickup (Ir), short-time pickup (Isd) and delay (tsd), and instantaneous pickup (Ii) via DIP switches on the front face. No external programming tool required — settings are read at a glance. For selectivity studies, the short-time delay allows the breaker to ride through downstream faults up to the Isd setting, letting a branch breaker clear first. The LSI curve suits motor feeder or distribution main applications where ground-fault (G) protection is handled separately or not required.
