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

Mersen Class H & K Fuse Reducers enable the use of lower rated fuses in existing electrical equipment that have clips rated for higher amperage. These fuse reducers improve circuit protection by allowing the installation of time-delay fuses sized closer to the motor nameplate current, enhancing system safety and reliability. Suitable for electrical distributors and lighting solutions providers, these reducers accommodate Class H, K, or R fuses fitting Class H or K clips. Rejection-type reducers restrict fitting to specific fuse classes and are not intended for bolt-on applications.
