Form 101 Semiconductor Protection
fuses are popular for the protection of higher voltage
heavy rectifiers such as traction rectifiers. They can
carry long sustained overloads common with heavy
duty apparatus. 700A through 2000A sizes are of
compact, hockey-puck design, able to provide high
power protection in a small space.
Features / Benefits

components during fuse clearing
®
Choice of mounting types
helps in equipment design
