Ferraz Shawmut glass fuse

For over a century, Ferraz Shawmut has been providing the world with fuses that are innovative and reliable. They offer a wide variety of products including power fuses, fuse holders, disconnect switches, power distribution blocks and surge suppression devices. Ferraz Shawmut has changed its name to Mersen. RSP Supply is a proud distributor of Ferraz Shawmut time delay and fast-acting fuses. Time delay fuses will carry an overload for a short period of time without blowing. These fuses are ideal for situations where acceptable momentary overloads are encountered, such as starting a motor. Fast-acting fuses blow immediately after the maximum rating of the fuse is exceeded. These fuses are ideal for protecting sensitive equipment.
