Cooper Bussmann KTK-R-10 Cc Fast-acting Fuse 10A 600V

Product Description

The COOPER BUSSMANN KTK-R-10 is a Class CC cartridge fast-acting fuse rated at 10 amps and 600 volts AC. It delivers a 200 kA interrupting rating, making it suitable for circuits where high fault-current protection is required. The cylindrical cartridge body measures 1.5 inches in length and 10.3 mm in diameter and mounts in a standard CC-class fuse holder. Electricians and controls technicians install this fuse in control panels, motor starters, and branch circuit protection applications where a Class CC rejection-style fuse is specified.

This fuse is used in industrial and commercial control circuit applications. Its rejection feature ensures it can only be installed in Class CC fuse holders, preventing accidental substitution with lower-rated fuse classes. Typical applications include protection of low-voltage control transformers, instrumentation circuits, and small motor control centers where fast-acting response to overloads and short circuits is required.

Key Features

• Class CC rejection design prevents installation in non-compatible fuse holders
• Fast-acting response for overload and short-circuit protection in control circuits
• 600-volt AC rating suitable for commercial and light industrial panel applications
• 200 kA interrupting rating at AC RMS for high fault-current environments
• RoHS compliant construction
• UL Listed, CSA Certified, and CE Certified for broad code compliance

Compatibility

Designed for use in Class CC fuse holders that accept the standard 10.3 mm diameter rejection-style cartridge fuse body.

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 before installation. Never replace a fast-acting fuse with a time-delay type unless the circuit protection requirements have been confirmed by a qualified engineer.
