Eaton CVH3225X3 Molded Case Circuit Breaker - 100 kAIC
Part Number: CVH3225X3
Quick Summary
CVH3225X3 is a molded case circuit breaker that protects industrial power distribution panels in commercial and light industrial facilities. Tripping during surges or overloads leads to costly downtime, and this breaker is designed for quick, predictable interruption. It carries CSA C22.2 No. 5 and UL 489 certifications, ensuring regulatory compliance and safer, reliable operation. These attributes, along with a 225 A rating and a CV frame three-pole design, support scalable protection, easier panel integration, and lower total cost of ownership. With easy integration into Eaton load centers and compatibility with Cu/Al conductors up to #6/0 and terminal shields for large feeders, it reduces installation risk and speeds commissioning.

FAQs
CVH3225X3 is designed for three-pole CV frame installations in Eaton load centers and compatible panels. Mounting follows standard MCCB procedures for molded case breakers, with wiring permitted up to #6-4/0 Cu/Al and a maximum load of 300 kcmil. For 300 kcmil wiring, refer to the catalog notes about using a terminal shield and adding 1.50 inches to the breaker length to ensure proper fitment and spacing.
Key ratings include a 225 A continuous rating and a 100 kAIC interrupt capacity, suitable for protecting feeders and motor circuits. The device is a three-pole molded case breaker with a CV frame, and accepts Cu/Al conductors up to #6-4/0 AWG with terminals rated to the same maximum load. This combination supports reliable short-circuit interruption and coordinated protection in typical industrial panels.
Yes. The CVH3225X3 is a three-pole molded case breaker built for three-phase protection in industrial power distribution. Its CV frame and 225 A rating make it suitable for service feeders and distribution duties in manufacturing lines, packaging, and other heavy-duty environments where reliable interruption is essential for equipment protection and uptime.
CVH3225X3 carries UL 489 and CSA C22.2 No. 5 certifications, signaling compliance with recognized safety and performance standards for low-voltage protection devices. This matters for regulatory approvals, safe commissioning, and audit readiness in industrial facilities and in customer-specified safety programs.
With a limited lifetime warranty and compatibility with standard Eaton components and load centers, CVH3225X3 reduces long-term maintenance costs and parts obsolescence risk. Its durable build and high interrupt rating minimize downtime, contributing to favorable ROI in projects requiring dependable protection and predictable lifecycle costs.
