Medium voltage or MV fuses are protection devices used in medium voltage switchgear. All fuses protect electrical devices and appliances from isolate sub-systems and overcurrents from the main system, which cause costly damages. The effectiveness of MV fuses stems from their rapid current-limiting ability in case of circuit failure.MV fuses usually have a voltage ranging from 1.5kV to 36kV. There are two types of MV fuses, current limiting, and expulsion fuses. Current limiting fuses interrupt current by introducing high resistance to limit the current magnitude and duration in case its current responsive element gets melted by the specified limiting range of current. Examples of MV fuses are full range, general-purpose, E- and R-Rated, and back-up fuses. They reduce both the magnitude of a fault current and the overcurrent event duration. Expulsion fuses are vented fuses that interrupt current via gasses expulsion effect from the internal arcing. Types of expulsion fuses include boric acid fuses and replacement fuse links.MRO Supply is your best bet at getting bins, carts, pallet jacks
