LA60X Semiconductor Fuses
600 VAC • Very Fast Acting • 700 – 2000 Amperes
Littelfuse LA60X 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. The compact “hockey puck” design provides high power
protection in a small space.
