Class H & K Fuse Reducer - H & K

Class H & K Fuse Reducer - Fuse Reducer for Electrical Circuit Protection Mersen Class H & K Fuse Reducers enable the use of lower rated fuses in existing equipment with clips rated for higher amperes. These reducers improve circuit protection by allowing the use of closer rated time-delay fuses, such as replacing renewable or one-time fuses feeding motors with fuses sized closer to motor nameplate currents. Non-rejection reducers accommodate Class H, K, or R fuses fitting Class H or K clips, while rejection-type reducers restrict fitting to Class R or Class J fuses in their respective clips. This product is designed for temporary use and is not suitable for bolt-on applications. Ideal for electrical distributors and switchgear suppliers seeking reliable fuse and circuit protection solutions.
