Cooper Bussmann KTK-R-2 Cc Class Fast-acting Fuse 2A 600V

Product Description

The COOPER BUSSMANN KTK-R-2 is a Class CC cartridge fast-acting fuse rated at 2 amps and 600 volts AC, with an interrupting capacity of 200 kA at AC RMS. It measures 1.5 inches in overall length and 10.3 mm in diameter, fitting standard Class CC rejection-style fuse holders. The fast-acting response characteristic makes it well suited for protecting sensitive control circuits and instrumentation where rapid overcurrent interruption is required. Licensed electricians and control panel technicians are the primary installers of this fuse type.

This fuse is designed for use in commercial and industrial control circuits, instrumentation panels, and HVAC equipment control boards where Class CC fuse holders are installed. The rejection feature ensures that only Class CC fuses can be inserted into compatible rejection-style holders, preventing accidental substitution with lower-rated fuse classes. It is appropriate for use in both new installations and service replacement applications wherever a 2-amp, 600-volt Class CC fast-acting fuse is specified.

Key Features

• Class CC cartridge form factor with rejection feature prevents substitution with non-CC fuse classes
• Fast-acting response for rapid overcurrent protection of sensitive control circuits
• Rated 600 volts AC with 200 kA interrupting capacity at AC RMS
• Compact size: 1.5 inches length, 10.3 mm diameter
• UL Listed 248-4 Class CC, CSA C22.2 No. 248.4 Certified, CE Certified, and RoHS Compliant

Compatibility

Designed for installation in rejection-style Class CC fuse holders. The rejection feature limits installation to holders specifically designed for the Class CC form factor, preventing use of non-CC fuse types in the same position.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local electrical codes. Always de-energize and lock out the circuit before removing or installing fuses. Verify that the fuse holder is rated for Class CC fuses and that the replacement fuse amperage and voltage rating match the circuit requirements exactly. Do not exceed the rated voltage or amperage for this fuse.
