Eaton Specification Sheet - CVH3225LL3
Feature → Business Impact → Application: The CVH3225LL3 offers a 225 A amperage rating, enabling it to serve as a tenant main breaker in multi-feed panelboards, which translates to reliable overload protection and reduced nuisance tripping during startup surges in commercial spaces. This supports faster commissioning and lower downtime in manufacturing lines, data centers, and retail facilities. Feature → Business Impact → Application: A 100 kAIC interrupt rating provides higher fault-current withstand, improving personnel safety and protecting downstream equipment during short circuits. This is vital for factory automation zones and utility-ted main feeders where fault currents can be substantial. Feature → Business Impact → Application: Three-pole design accommodates three-phase systems, simplifying integration in standard low-voltage power centers and enabling balanced protection across phases. This aligns with industry best practices for MV/LV distribution in industrial plants and data-safe environments. Feature → Business Impact → Application: CV frame compatibility and terminals rated for #6-4/0 AWG Cu/Al with #300 kcmil load and line conductors enable straightforward field wiring and reduced installation time, cutting labor costs and accelerating project timelines in new builds or panel upgrades. Feature → Business Impact → Application: The compact footprint—11.28 in long, 6.2 in high, 6.3 in wide—offers flexible mounting in tight enclosures, improving space utilization in crowded electrical rooms or retrofit projects. Feature → Business Impact → Application: UL 489 and CSA Std. C22.2 No. 5 certifications provide regulatory alignment and procurement confidence, supporting compliance audits and reducing supplier risk for regulated facilities. Feature → Business Impact → Application: A limited lifetime warranty adds long-term value, lowering lifecycle maintenance costs and offering reassurance for sustainability-focused programs in industrial environments.
