ATO® 257, Maxi® 299, Mini® 297 Series, Circuit Protection Kits - Fuse

Circuit protection fuse kits comprise devices engineered to interrupt current flow between two terminals when it surpasses a predetermined threshold, thereby creating a physical open circuit condition. This interruption occurs as the conductive material between the terminals melts (blows) due to the heat generated by excessive current flow. Fuse varieties include those with an immediate open circuit response, known as fast blow fuses, as well as those with a delayed open response, termed slow blow fuses.
