LA60X Semiconductor Fuses 600 VAC ■ Very Fast-Acting ■ 700 – 2000 Amperes SPECIFICATIONS Voltage Rating: AC: 600 volts Interrupting Rating: AC: 100,000 Amperes Ampere Range: 700 – 2000 Amperes Approvals: UL Recognized under the components program. NEW AMPERE RATINGS 700 800 1000 1200 1500 1600 1800 2000 ORDERING INFORMATION (Hockey Puck, bolt-in) Mounting Type Ampere Rating Littelfuse’s 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. Style Littelfuse Voltage (600) LA 60 X 700 -128 FIGURE 1 FEATURES ■ ■ Lowest I2t minimizes damage to protected components on short circuit. Controlled arc voltage reduces stress to circuit components during fuse clearing. FIGURE 2 APPLICATIONS Protection of heavy traction and electrochemical as well as rectifiers and other heavy-duty equipment. DIMENSIONS Dimensions for reference only. AMPERES MOUNT. TYPE FIG.
