In a 400 V distribution board, 25 kA covers most commercial and light industrial service-entrance conditions; if your available fault current runs higher, you would step up to the XT1H or XT1L series with 36 kA or 50 kA ratings. Its compact 3-pole footprint (45 mm per pole) fits standard distribution boards and motor control centers. The line and load terminals accept copper or aluminum conductors up to 50 mm², with a torque rating of 3.5 Nm for the main connections. For field-service swaps, the breaker's plug-in base option allows replacement without disturbing the busbar connections — a time-saver on a live panel during a line-down event.","metaTitle":"ABB XT1NU3110AFF000XXX XT1N 3-Pole MCCB, 25 kA IC","metaDescription":"ABB XT1NU3110AFF000XXX 3-pole MCCB with 25 kA interrupting capacity at 400 VAC.

It determines the available fault current your panel can withstand at the breaker's line side — critical for UL 508A SCCR compliance and selective coordination with downstream devices."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/XT1NU3110AFF000XXX","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/XT1NU3110AFF000XXX when reusing this data.
