LA60X1000128

Special Purpose Fuses 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 I2t 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.
