Cooper Bussmann KTK-10 Cartridge Fast-acting Fuse 10A 600V

Product Description

The COOPER BUSSMANN KTK-10 is a cartridge-style, fast-acting general purpose fuse rated at 10 amps and 600 volts AC. It is designed for current-limiting overcurrent protection in control circuits, industrial equipment, and electrical panels where fast response to overloads and short circuits is required. The fuse body is constructed from melamine, measuring 1.5 inches in overall length and 10.3 mm (approximately 0.406 inches) in diameter. With an interrupting rating of 100 kA at AC, it is suited for installations where high fault-current capacity is a specification requirement. Electricians and controls technicians are the primary installers of this fuse type.

The KTK-10 is applied in fuse holders across residential, commercial, and light industrial electrical systems. Common applications include machine tool control circuits, transformer primary protection, and low-voltage control panel wiring where a fast-acting fuse is specified. Its compact cartridge form factor fits standard inline and panel-mount fuse holders designed for this diameter class. The melamine body provides resistance to heat and arc products during a fault event, making it appropriate for repetitive-duty control circuit protection.

Key Features

• Fast-acting fuse timing for rapid response to overloads and short-circuit conditions
• 10 amp rating with 600 volt AC maximum voltage
• 100 kA interrupting rating at AC for high fault-current applications
• Melamine body construction for thermal and arc resistance
• Compact cartridge form: 1.5 inches long, 10.3 mm diameter
• Mounts in standard fuse holders; no tools required for replacement

Compatibility

Designed for use in fuse holders that accept cartridge-style fuses with a 10.3 mm body diameter and 1.5 inch overall length, typical of KTK-series class fuse holder applications.

Installation Notes

Installation and replacement of this fuse should be performed by a qualified electrician in accordance with NFPA 70 (NEC) requirements. Always de-energize and lock out the circuit before removing or installing a fuse. Verify that the replacement fuse amperage and voltage ratings match the circuit requirements before reinstalling. Use an appropriately rated fuse puller when removing the fuse from its holder to avoid contact with energized components.
