Mersen 700VAC Class J Time Delay AJT Fuses

February 11, 2022

Mersen is pleased to announce improvements to its AJT series of fuses (15-100 Amp models), enabling an increase in AC operating voltage from 600VAC to 700VAC. This has been done primarily to better accommodate power transmission networks at 585V or 600V, especially common in Northeast Canada and the Midwest US.

Mersen’s Class J AJT fuses are compact fuses that offer big protection. The most current-limiting UL-class fuse, Mersen’s AJT series provides optimal performance and saves valuable panel space. Their time-delay characteristic allows for use in a wide range of applications. AJT fuses are available in indicating and non-indicating versions.

Mersen is the only fuse manufacturer to offer Class J fuses with the 700VAC specification. The fuses have been UL self tested. There will be no change in part numbers or pricing. The new 700VAC specification will be available in 15-100A AJT fuses as of the manufacturing date of February 14, 2022.
