Fuse rails NV/NH are 3-pole bases designed to house low-voltage (LV) fuse links. These fuse rails provide a secure and efficient method for organizing and protecting multiple fuse links in various electrical systems. Their primary application lies in cable distribution and power supply systems.The main function of NV/NH fuse rails is to ensure circuit protection by interrupting the flow of electricity during overload or short-circuit events. This protective measure safeguards connected devices and equipment from potential damage caused by excessive current.
