Mersen provides circuit protection products including low and medium voltage fuses, cable protectors, and switching products to protect against arch flash.
What is Arc Flash?
An arc flash hazard is defined by the National Fire Protection Association (NFPA) as “a dangerous condition associated with the release of energy caused by an electric arc.” To learn more about Arc Flash and what Renmark can do for you, click here.

The fuses Mersen recommends for arc flash energy reduction are UL Listed branch circuit fuses with the highest degree of current limitation. The fuses shown below 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:
Designed for applications greater than 600 amperes, A4BQ offers an interrupting rating of 300 kA and a unique design that delivers excellent performance in arc flash situations. For more information visit Amp-Trap 2000 A4BQ Class L Fuse.
The ideal choice for new applications of 600 amperes and less, AJT offers excellent current-limiting performance for short circuits and time delay for overloads. The unique Class J dimensions prevent improper substitutions. For more details, visit Amp-Trap 2000 AJT Class J Fuse.
The ideal choice for upgrading existing applications of 600 amperes and less, the A6D offers excellent current-limiting performance for short circuits and time delay for overloads. Its dimensions allow for simple upgrades of existing Class H, Class K and Class RK5 fuses. For more details, visit Amp-Trap 2000 A6D Class RK1 Fuse.
