700VAC Class J Fuses

Mersen's Class J AJT fuses are compact fuses that offer superior protection. The AJT series offer increased AC operating voltage from 600VAC to 700VAC, meeting the needs of power transmission networks at 585V or 600V.

Mersen is the only fuse manufacturer to offer Class J fuses with the 700VAC specification.

• In some cases, customers encounter voltage variations above 600 volts. Our self-certified Class J AJT fuse rated at 700 volts will safely operate under overload or short circuit conditions.

• Voltages may fluctuate due to large inrush currents caused by motors that draw large currents during startup.

• Many of the mining, forestry, and other “heavy” industries have a 600V nominal voltage, which means there can be a variation up or down from nominal voltage.

• CSA Standard CSA-C235-83 allows for service entrance variation to go from 530V to 635V.

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

Compact Fused Switches

The next level of safety and ease of installation

Mersen’s Compact Fused Disconnect incorporates the switch functionality with the high protection level of a fuse. The switch accepts UL class CC fuses up to 30A. In addition to this, the Compact Fused Disconnect is UL 98 listed and suitable for use as main/feeder device and, in conjunction with CC fuses, is rated for branch circuit protection.

It has a smaller footprint compared to a traditional Class CC disconnect with a max interrupting rating of 200kA. The compact form factor and ease of installation makes it a great choice for panel builders. The easy lockout/tagout feature and IP20 rating ensures additional safety along with the built in switch capability.
