Class H & K Fuse Reducer - H & K

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 amperes, improving circuit protection by allowing closer rated time-delay fuses. These reducers are suitable for electrical distributors and switchgear suppliers looking to optimize fuse sizing, such as replacing renewable or one-time fuses feeding motors with fuses sized closer to motor nameplate current. Non-rejection reducers permit Class H, K, or R fuses to fit Class H or K clips, while rejection-type reducers restrict fit to Class R or Class J fuses, depending on clip compatibility. Note that Class J fuse reducers are not intended for bolt-on applications.
