A fuse has two main functions: One, to protect your components, equipment and you from risk of fire or electric shock caused by over-currents. Two, they stop a chain reaction from occurring in the main system once a fault has occurred. Fuses can help make your control systems meet the newest UL and NEC codes, such is the case with Cooper Bussmann FNQ Series of fuses. These are midget fuses that are specifically designed transformers and circuits with in-rush currents. |
