— CR305, CR385 magnetic contactors Factory-installed modifications

Factory-installed auxiliary contacts The final letter of the Product Number denotes extra auxiliary contacts (sometimes referred to as auxiliary interlocks). Order the desired extra auxiliary contacts, factory installed on the contactor, by replacing the final letter of the Product Number with a letter from the first column of the auxiliary contact table. If a CR305 or 306 Product Number has no 3-letter suffix, first add an “AAA” suffix, and then substitute a letter from first column of the auxiliary contact table. Example: CR306C022 becomes CR306C022AAD for a Size 1 contactor with one extra NO and one extra NC auxiliary contact.
