Reducing Arc Energies with Fuses - Mersen

Typically, the fuses we recommend for arc flash energy reduction are UL Listed branch circuit fuses with the highest degree of current limitation. The fuses shown here have had excellent results in laboratory tests, limiting arc flash incident energies to very low values for arc fault currents within their current-limiting range.

A. Conventional 15 kV Class fuses: Mersen HMH (9F60HMH). These are available in 65E, 80E and 100E, therefore, work through 1500 kVA. B. If the incident energy must be reduced further, in lieu of the HMH fuse, the new Mersen Medium Voltage Controllable Fuse can be use. This is a hybrid fuse that is relay controlled in the arc flash mode.
