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 designed for higher ampere ratings. These fuse reducers improve circuit protection by allowing closer rated time-delay fuses to be used, such as replacing renewable or one-time fuses feeding a motor with fuses sized closer to the motor nameplate current. Designed for compatibility with Class H and K clips, these reducers help electrical distributors and switchgear suppliers optimize fuse sizing without modifying existing equipment.
