Bussmann Class RK5 Time-Delay Fuse

The Bussmann Class RK5 time-delay fuse line provides dependable overcurrent protection for motor circuits, transformers, and other electrical equipment. These dual-element, current-limiting cartridge fuses (also called RK5 time delay fuses) are made for circuits that see temporary inrush currents. The time-delay design lets the fuse ride through brief motor-starting surges and overloads. It still opens quickly on sustained overloads and short circuits.

Key Features:

• Class RK5 current-limiting design that helps reduce let-through energy during fault conditions
• Dual-element, time-delay construction that tolerates motor starting inrush without nuisance opening
• Protects against both overloads and short circuits
• Cartridge-style construction for use in standard Class R fuse holders and fuse blocks
• Available in multiple amperage and voltage ratings across the line
• Made by Bussmann, a long-established brand in circuit protection

These fuses suit industrial, commercial, and HVAC applications that need dependable, time-delay circuit protection. Check the amperage and voltage rating of the specific part number you need before you order.
