Cooper Bussmann BP/KTK-20 Fast Acting Fuse 20A 5 Pack

Product Description

The COOPER BUSSMANN BP/KTK-20 is a 20-amp Type KTK fast-acting fuse designed for overcurrent protection in control circuits, instrumentation, and light industrial equipment. Fast-acting fuses respond immediately to overloads without the intentional time delay found in slow-blow designs, making them the correct choice where connected components cannot tolerate sustained fault current. This carded pack contains 5 fuses, providing immediate replacement stock for service technicians working on motor control panels, HVAC equipment controls, or low-voltage circuit boards. The KTK series is a widely recognized ferrule-style fuse format used throughout trade and industrial applications.

This fuse is suited for residential and light commercial applications where KTK-class fast-acting overcurrent protection is specified. Common install scenarios include control panels, transformer secondary circuits, and instrumentation wiring where branch-circuit protection must react quickly to protect sensitive downstream components. The carded retail-style packaging makes it convenient for field stock or counter sales. Licensed electricians and HVAC technicians are the primary installers of this fuse type.

Key Features

• 20-amp fast-acting KTK series fuse for immediate overcurrent response
• Ferrule-style form factor compatible with standard KTK fuse holders
• Carded 5-pack format for field stock and service inventory
• No intentional time delay — opens quickly to protect sensitive control components
• Compact dimensions suitable for use in tight panel and equipment enclosures

Compatibility

Designed as an OEM-style replacement for standard KTK-class fast-acting ferrule fuses used in control circuit and instrumentation applications where a 20-amp fast-acting fuse is specified.

Installation Notes

De-energize and lock out the circuit before replacing any fuse. KTK ferrule fuses are installed and removed using an appropriate fuse puller — do not use bare hands or uninsulated tools. Verify the replacement fuse amp rating and type match the original specification exactly before restoring power. Electrical work involving panel components should comply with applicable NEC requirements and local codes.
