Cooper Bussmann KTK-R-15 Cc Fast-acting Fuse 15A 600V

Product Description

The COOPER BUSSMANN KTK-R-15 is a Class CC cartridge fast-acting fuse rated at 15 amps and 600 volts AC. Designed for general-purpose overcurrent protection, it delivers an interrupting capacity of 200 kA at AC RMS, making it suitable for circuits where high fault-current protection is required. The cartridge body measures 10.3 mm in diameter and 1.5 inches in overall length. It mounts in a standard CC-class fuse holder with a rejection feature that prevents substitution of non-CC fuses, maintaining system integrity. Licensed electricians and industrial maintenance technicians are the primary installers of this component.

This fuse is used in control circuits, motor branch circuits, and industrial equipment applications where Class CC ratings are specified. The fast-acting response characteristic makes it well suited for resistive loads and control panel protection where speed of interruption is critical. It is sold individually but must be ordered in multiples of 10 per manufacturer minimum order requirement.

Key Features

• Class CC fast-acting cartridge fuse with rejection feature prevents substitution of lower-rated fuse classes
• 15-amp rating with 600-volt AC capacity for control and branch circuit protection
• 200 kA interrupting rating at AC RMS for high fault-current applications
• Compact 10.3 mm diameter body fits standard CC fuse holders
• UL Listed 248-4 Class CC, CSA Certified, CE Certified, and RoHS Compliant

Compatibility

Designed for use in CC-class fuse holders with rejection-style mounting. The rejection setting prevents installation in non-CC holders, ensuring proper class-specific circuit protection.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before removing or installing any fuse. Verify that the fuse holder is rated for Class CC cartridge fuses before installation. Never bypass or replace with a fuse of a different class or higher amperage rating than the circuit design specifies.
