Littelfuse FLSR175ID 600V 175A Time Delay Class RK5 Fuse

The Littelfuse FLSR175ID is a dual-element, time-delay fuse rated for 600 volts AC and 175 amperes. This industrial-grade fuse features Class RK5 construction with current-limiting and time-delay characteristics, providing superior protection for motor circuits, transformers, and other inductive loads subject to high inrush currents.

Key Features:

• 600V AC voltage rating with 175A ampere rating
• Dual-element time-delay design allows temporary overloads while protecting against short circuits
• Class RK5 current-limiting fuse with 200,000 AIC interrupting rating
• Designed for industrial applications with high inrush currents
• UL Listed and CSA Certified for safety compliance
• Bolt-in mounting style for secure installation in disconnect switches and panelboards

This time-delay fuse is ideal for protecting motors, welders, transformers, and other equipment where temporary overloads are normal during startup. The current-limiting design helps protect downstream equipment and reduces arc flash hazards by quickly interrupting fault currents.
