What this table does not tell youMatching ratings do not make two parts interchangeable. Frame size, terminal layout, accessories, approvals (UL/CSA/VDE) and derating differ between manufacturers, and manufacturers do not certify third-party equivalents. Check the data sheet of the part you intend to use, or send us the original part number and we will confirm.
