The order code breaks down as XT5H (frame series), U (UL/CSA version), 3 (3-pole), 25 (250 A trip rating), AFFF (fixed front terminals, FF designation), 000XXX (variant suffix). This is the UL/CSA-certified variant, meaning it carries the approvals for North American panel builds. ## What the EKIP DIP LSI trip unit means for coordination The EKIP DIP LSI trip unit is an electronic, adjustable type offering L (long-time delay), S (short-time delay), and I (instantaneous) protection functions. For a panel OEM or site electrical engineer, this means you can set the short-time pickup and delay to achieve selective coordination downstream — critical for avoiding nuisance tripping on a feeder serving motor loads or distribution panels. The 250 A rating on a 400 A frame gives you headroom for future load growth without swapping the breaker body. ## Panel integration and terminal style Fixed front terminals (FF) mean the line and load connections are at the front of the breaker, suitable for panel layouts where rear or plug-in connections aren't available. Verify the terminal screw torque and conductor size per the ABB installation manual for the 250 A continuous rating.","metaTitle":"ABB XT5HU325AFFF000XXX XT5H 400A MCCB, EKIP DIP LSI 250A","metaDescription":"ABB XT5HU325AFFF000XXX XT5H 400A frame MCCB with EKIP DIP LSI trip unit, 250A rating, 3-pole.
