Supplemental Fuses
These are fuses which are also described as miscellaneous, miniature, and micro fuses. They provide supplemental protection in end-use equipment which add another level of protection for components or internal circuits. These are not for use in branch or feeder circuit use. There are no specific physical dimensions specified, and dimensional limitations apply to prevent insertion of supplementary protection fuses into branch or feeder circuit fuse holders intended to accommodate branch or feeder circuit fuses of the Class CA, CB, CC, CD, G, H, J, K, L, R or T Type.
