Fluke 943121 Fuse Cartridge 440 Ma 1KVAC

Product Description

The FLUKE 943121 is a fuse cartridge rated at 440 milliamps (mA) and 1 KVAC, designed as a replacement protection component for Fluke test and measurement instruments. Fuse cartridges of this type protect sensitive internal circuitry from overcurrent events during electrical measurement work. Installation and replacement are performed by licensed electricians and instrumentation technicians as part of routine meter maintenance. The 440 mA current rating and 1 KVAC voltage rating make this cartridge appropriate for high-voltage measurement environments.

This fuse cartridge is used in field and shop settings where Fluke meters and test instruments require fuse replacement after an overcurrent fault. It is a common service item for electricians, industrial maintenance technicians, and calibration labs that rely on Fluke measurement equipment. Proper fuse selection by current rating and voltage class is critical to maintaining safe and accurate meter operation.

Key Features

• Rated at 440 mA for precise overcurrent protection
• 1 KVAC voltage rating suitable for high-voltage measurement environments
• Cartridge form factor for straightforward replacement in compatible Fluke instruments
• Protects sensitive meter circuitry from overcurrent damage

Compatibility

Designed as an OEM-style replacement fuse cartridge for compatible Fluke test and measurement instruments requiring a 440 mA, 1 KVAC cartridge fuse.

Installation Notes

Fuse replacement in test instruments should be performed by a qualified technician. Always power down and disconnect the meter from any circuit under test before accessing the fuse compartment. Verify the replacement fuse matches the original current rating and voltage class as marked on the instrument. Using an incorrect fuse rating can compromise meter safety and accuracy and may void instrument certification.
