March 3, 2022 – Mersen says it has improved its AJT series of fuses (15A to 100A)—enabling an increase in AC operating voltage from 600VAC to 700VAC—primarily to better accommodate power transmission networks at 585V or 600V, “especially common in Northeast Canada”.

Mersen’s AJT series promises optimal performance while saving valuable panel space. Their time-delay characteristic allows for their use in a range of applications, and they are available in indicating and non-indicating versions.

The company says it is the only fuse manufacturer to offer Class J fuses with the 700VAC spec. Additionally, there will be no change in part numbers or pricing.
