175 A, 65 kA — the interrupting rating that decides the fit
The ABB XT4HQ3175AFF000XXX is a 3-pole molded case circuit breaker from the XT4H 250 TMF family, rated 175 A continuous at 480 VAC. Its 65 kA interrupting capacity at 480 V means it can safely clear a fault up to that level without upstream fuses or a larger frame — a spec that governs panel SCCR and selectivity coordination. Panel-mount construction suits it for switchboard or distribution panel integration where a DIN-rail breaker won't carry the current.
