FRN-R-40 - 40 Amp Fuse Description
FRN-R-40 - 40 Amp Fuse
The FRN-R-40 is a 40-amp Class RK5 dual-element fuse with ferrule ends and a non-indicating configuration. The physical fit is equally easy to verify: the FRN-R-40 measures 3 inches long, 0.81 inches high, and 0.81 inches wide. If you're comparing the fuse in your equipment with the specifications on the page, the dimensions, ferrule connections, Class RK5 designation, and electrical ratings provide several solid points for identification before installation.

Where It Works Best
- Equipment specifications calling for the FRN-R-40 or the same complete set of electrical and physical characteristics.
- 40A Class RK5 fuse positions that accept ferrule connections and the fuse's 3 × 0.81 × 0.81-inch dimensions.
- 250V AC circuits where a 200 kAIC at 250V AC interrupting rating satisfies the circuit requirements.
- 125V DC circuits where the published 20 kAIC at 125V DC rating and remaining specifications are suitable.
- Installations specifying a dual-element, non-indicating fuse with the FRN-R-40's stated response characteristic.
