Class H & K Fuse Reducer - Fuse Reducers for Electrical Protection

Mersen Class H & K Fuse Reducers enable the use of lower rated fuses in existing equipment with clips rated for higher amperages. These fuse reducers improve circuit protection by allowing closer rated time-delay fuses to be installed, such as replacing renewable or one-time fuses feeding motors with fuses sized closer to the motor nameplate current. This product is suitable for electrical distributors and switchgear suppliers seeking precise fuse sizing solutions to enhance protection and equipment compatibility.
