Bussmann KTK-R-1/4 Midget Fuse

Bussmann KTK-R-1/4 Midget Fuse, 600V, 1/4A Rating

The Bussmann KTK-R-1/4 is a 600V-rated midget-style fuse engineered to deliver precise, dependable overcurrent protection at a 1/4A (0.25 Amp) rating. Built to the industry-standard midget fuse footprint, the KTK-R-1/4 is designed for electricians, panel builders, and OEMs who need a compact, reliable protective device that fits standard midget fuse holders, fuse blocks, and disconnect switches. As part of the recognized Bussmann KTK-R product family, this fuse is well suited to applications where a small footprint and a low current rating are required to protect sensitive control, instrumentation, and low-current circuits from damaging overcurrent conditions. The defined 600V voltage rating and 1/4A current rating make it easy to specify the correct protective device for a given circuit.

Key Features

• Amperage Rating: 1/4A (0.25 Amp) rating suited to protecting low-current control and instrumentation circuits from overcurrent damage.
• Voltage Rating: Rated for use on systems up to 600V, giving installers flexibility across a range of circuit voltages.
• Midget Fuse Form Factor: Compact midget-style body fits standard midget fuse holders, blocks, and disconnects commonly found in industrial and commercial panels.
