Reducing arc flash hazard using current limiting Fuses
- The fuse industry has responded with new classes of fuses that reduce the incident energy, and the radius of any arc flash blast – which improves safety and reduces the level of personal protective equipment that workers are required to wear
- Reducing ARC Energy with current limiting fuses
- National Fuse supplier Ferraz-Shawmut, a world leader in current limiting fuses, describes how arc flash can be reduced with current limiting fuses
http://us.ferrazshawmut.com/arcflash/reducing_arc_energies/current_limiting_fuses.cfm - Understanding current limitation
- A technical description of current limitation
http://us.ferrazshawmut.com/arcflash/reducing_arc_energies/current_limitation.cfm - Ferraz-shawmut recommended fuses
- Ferraz Shawmut has 3 families of current limiting fuses
http://us.ferrazshawmut.com/arcflash/reducing_arc_energies/current_limitation.cfm - ARC Flash Calculator
- This ARC flash calculator shows the benefits of Ferraz-Shawmut current limiting fuses. The calculator uses IEEE calculations for the incident energy – which is much lower than older fuses – and references the level of PPE required which is less restrictive and more comfortable for your workers
http://us.ferrazshawmut.com/arcflash/reducing_arc_energies/calculator.cfm - Ferraz – Shawmut fuse consolidation graphic
- The universal Class RK1 product family replaces a wide array of older fuses -- and results in the least prohibitive NFPA70E Arc Flash boundary.

Personal Protective Equipment
- Selecting PPE
- Making personal protective equipment available for your workers is the responsibility of the employer – there are two basic approaches to selecting the appropriate equipment
http://us.ferrazshawmut.com/arcflash/hazard_analysis/why_hazard_analysis.cfm - Task Table from NFPA 70E
- This task table – extracted from NFPA 70E – specifies for workers the appropriate protective equipment based on the task they are performing. Using this task table eliminates the need for detailed calculations.
