For example, the indicating fuse has a voltage rating of volts. This fuse can be used on 600 volts, 480 volts, 250 volts, 125 volts, or 75 volts. Never use a fuse in a circuit having a higher rated voltage than the fuse. * Check specific mounting dimensions before substituting. Check characteristics and dimensions for application before substituting. For 1 /10-30 amperes, order non-indicating FLNR series fuses. Verify voltage for DC applications. + Littelfuse product is a non-renewable fuse Littelfuse POWR-GARD Products Catalog

Motor Protection Effective motor protection is critical in today s highly automated industrial facilities. POWR-GARD fuses and protection relays provide optimum protection for motors in main, feeder, and branch circuits. SCCR The NEC requires Industrial Control Panels be labeled with their Short-Circuit Current Rating so users and inspectors can compare their equipment to available fault currents to avoid potential hazards. Transformer Protection POWR-GARD fuses provide optimal overcurrent protection for both the primary and secondary of control transformers and other regular transformers above and below 600 volts. Arc-Flash Protection Arc-flash protection relays are intelligent controllers that safeguard equipment and personnel to prevent damage, downtime or injury due to arc flash. Medium Voltage Fuse Protection POWR-GARD medium voltage fuses provide short-circuit protection for motors and transformers rated 2,400 to 38,000 Vac. Overvoltage Suppression Basics Overvoltage conditions are an increasing concern in the electrical industry. Littelfuse has a diverse portfolio of circuit protection technologies to protect against voltage transients in multiple applications.
