Cooper Bussmann KTK-R-6 Cc Class 6A 600V Fast-acting Fuse

Product Description

The COOPER BUSSMANN KTK-R-6 is a Class CC cartridge fast-acting fuse rated at 6 amps and 600 volts, with an interrupting capacity of 200 kiloamps at AC RMS. Designed for general-purpose overcurrent protection, this rejection-style fuse mounts in a standard CC-class fuse holder and provides fast-acting response to fault conditions. Its compact cartridge body measures 1.5 inches in overall length and 10.3 mm in diameter. Electricians and controls technicians install this fuse in motor control panels, HVAC control circuits, and industrial equipment where Class CC fusing is specified.

The KTK-R-6 is suited for residential and light commercial electrical panels, HVAC equipment control boards, and industrial control enclosures where Class CC fast-acting fuse protection is required. The rejection feature prevents installation of non-CC fuses in CC-rated fuse holders, maintaining system integrity and code compliance. This fuse is a common choice for low-amperage branch circuit and control circuit protection across a wide range of trade applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before removing or replacing any fuse. Verify the fuse holder is rated for Class CC fuses and confirm the circuit voltage and amperage are within the fuse rating before energizing. Never bypass or substitute a fuse with a higher amperage rating than the circuit design specifies.
