FAQs
Consider the CVH3225KX3's 225 A rating, three-pole design, CV frame, and terminal capacity of #300 kcmil maximum load (with a shield for 300 kcmil options). Verify panel space is sufficient for the 11.68 in length, 6.2 in height, and 6.3 in width, and ensure conductor sizes match the #6-4/0 AWG Cu/Al range.
This breaker is certified UL 489 and CSA C22.2 No. 5, indicating compliance with essential safety and performance standards for low-voltage circuit protection. These certifications support regulatory approvals, safe maintenance practices, and warranty eligibility in regulated environments.
Plan for a CV frame-compatible installation with three conductive paths, ensure proper torque on #6-4/0 AWG conductors, and account for the 300 kcmil terminal option if using larger feeders. Remember catalog notes: 300 kcmil options need a terminal shield and add 1.50 inches to the breaker length.
Yes. The 225 A rating, three-pole configuration, and CV frame design are well-suited for motor control centers and industrial load centers, providing reliable short-circuit and overload protection while supporting diverse conductor sizes and straightforward maintenance.
Beyond the unit price, consider installation time saved by compatible CV frame design, reduced downtime from reliable protection, and the limited lifetime warranty. The CI-based benefits include fewer field rewires, lower annual maintenance costs, and straightforward component replacement in mature electrical distributions.
