LESRK4I - 4 Amp Fuse Description
LESRK4I - 4 Amp Fuse
When you’re matching a replacement fuse, amperage is only one piece of the puzzle. The LESRK4I is a 4-amp, 600V AC Class R fuse with a time-delay, current-limiting design and an indicating configuration. Before installation, check the 4A rating, 600V AC voltage rating, Class R designation, time-delay characteristic, current-limiting design, indicating configuration, interrupting rating, and physical dimensions. It’s a simple check, but an important one when you need the electrical characteristics and physical fit to match the application.
Key Features and Benefits
- 4A rating for equipment or circuits requiring a 4-amp fuse
- 600V AC rating for applications specifying this voltage level
- Class R, current-limiting fuse configuration
- Time-delay characteristic as specified for the LESRK4I
- Indicating design for applications requiring an indicating fuse
- Cartridge-style construction

Material Compliance and Certifications
No specific material-compliance information or certification listings were included in the supplied LESRK4I specifications. Rather than add a certification that may not apply to this exact part number, confirm any required compliance or certification status against authoritative product documentation.
Where It Works Best
The LESRK4I is for electrical equipment or circuits requiring a 4A, 600V AC, time-delay Class R fuse with a current-limiting design, indicating configuration, and 200 kA interrupting rating. Also compare its cartridge-style construction and 5.0 x 0.81 x 0.81-inch measurements with the physical requirements of the existing installation.
For replacement applications, don’t stop at seeing “4A” on the fuse. Also compare the voltage, Class R designation, interrupting rating, time-delay characteristic, current-limiting configuration, indicator type, and dimensions. This gives customers useful information to determine whether the LESRK4I matches the specifications their equipment actually calls for.
