DMM-B-11A FLUKE MULTIMETER FUSE

Product Description

The DMM-B-11A is a high-energy fast-acting cartridge fuse used in Fluke digital multimeters and other precision test instruments. It is designed specifically to protect the current measurement input circuit from high fault currents while maintaining safety at high voltages.

It is a special-purpose meter fuse, not a general electrical fuse, and is engineered to safely interrupt very high fault levels inside measurement equipment.
