Cooper Bussmann KTK-6 Cartridge Fast-acting Fuse 6A 600V

Product Description

The COOPER BUSSMANN KTK-6 is a cartridge-style, fast-acting general purpose fuse rated at 6 amps and 600 volts AC. It features a melamine body measuring 1.5 inches in length and 10.3 mm (approximately 0.406 inches) in diameter. The fast-acting design provides rapid overcurrent interruption with a 100 kA AC interrupting rating, making it suitable for protecting sensitive equipment and branch circuits where quick response to fault conditions is required. Electricians and instrumentation technicians install this fuse in fuse holders designed for midget-style cartridge fuses across industrial, commercial, and control panel applications.

This fuse is used in control circuits, instrumentation panels, motor control centers, and light-duty branch circuit protection where a compact midget cartridge form factor is required. Its 600-volt rating covers a wide range of single-phase and three-phase low-voltage control circuit applications in both commercial and light industrial environments. The fuse mounts in a compatible fuse holder and is commonly found in HVAC control panels, electrical distribution boards, and machine control enclosures requiring fast overcurrent protection.

Compatibility

Designed for use in fuse holders that accept midget-style cartridge fuses with a 10.3 mm diameter and 1.5 inch body length. Verify fuse holder specifications before installation to confirm dimensional and voltage rating compatibility.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before removing or installing any fuse. Confirm the fuse holder is rated for the full 600-volt, 6-amp, and 100 kA interrupting capacity of this fuse. Never replace a fuse with one of a higher amperage rating without verifying circuit protection requirements.
