Eaton Specification Sheet - CVS3225LL3
High-current protection is paired with dependable fault interruption in the CVS3225LL3. The 225 A amperage rating and 42 kAIC interrupt rating translate to rapid fault clearance for feeders and motor circuits, reducing arc energy and downstream damage. In manufacturing lines and process facilities, this three-pole main breaker reliably guards main feeders and distribution panels while supporting CV frame compatibility and easy integration with existing equipment. CV frame family design optimizes field service and spare-part strategy. The molded case construction delivers compact form factor without sacrificing interrupt performance, enabling straightforward replacement in legacy switchgear and new installations. Engineers benefit from consistent trip curves, predictable coordination with downstream protective devices, and simplified testing during commissioning. Conductor versatility is built into CVS3225LL3 with terminals rated for #6-4/0 AWG Cu/Al and up to #300 kcmil line and load. This accommodates large feeders and high-capacity bus-bar connections common in distribution panels. The design supports secure, torque-controlled terminations that reduce loose connections and ongoing maintenance costs.

FAQs
CVS3225LL3 supports CV frame mounting in three-pole configurations, with #6-4/0 AWG Cu/Al conductors and #300 kcmil terminal capacity for line and load. It fits Eaton CV accessories and standard bus-bar layouts, enabling straightforward substitution in existing panels or during new builds. Verify terminal torque per wiring guidelines.
The 225 A rating indicates continuous operating current capability, while 42 kAIC is the maximum fault current the breaker can interrupt without damage. In motor feeder applications, this combination provides safe cutoff under short circuits and minimizes arc energy, supporting safe start-up and reducing downtime.
This breaker is UL 489 and CSA Std. C22.2 No. 5 certified, confirming conformity to recognized electrical-safety and performance standards. For panelboards, switchgear, and industrial control systems in regulated facilities, these certifications simplify procurement, testing, and end-user acceptance, ensuring consistent adherence to safety requirements.
With a robust molded-case design, compact CV frame, and secure #6-4/0 terminations, CVS3225LL3 resists thermal cycling and reduces loosening connections. Its high interrupt rating minimizes arc energy, while the limited lifetime warranty offers long-term protection against component degradation, lowering maintenance interruptions and replacement costs.
Although initial cost may be higher than lower-rated devices, the CVS3225LL3 reduces downtime through higher fault-clearance performance, lowers field service visits due to reliable terminations, and simplifies compliance testing with UL/CSA certification. Over a typical decade, total cost of ownership improves due to fewer outages and longer service intervals.
