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.
Features
• Lowest I 2 t minimizes damage to protected components on
short- circuit.
• Controlled arc voltage reduces stress to circuit components during
fuse clearing.
Applications
Protection of heavy traction and electrochemical as well as rectifiers and
other heavy-duty equipment.
