Amp Trap 2000 Fuses

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:

PHP-A4BQ1200-Amp-Trap-2000-MersenAmp-Trap 2000® A4BQ Class L Fuse

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. 

 

PHP-AJT-Time-Delay-Class-J-MersenAmp-Trap 2000® AJT Class J 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

 

MersenRk1nAmp-Trap 2000® A6D Class RK1 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.
