Mersen A6T10 Class T Fast-Acting Fuse, 600VAC/300VDC

Mersen A6T10 Class T Fast-Acting Fuse, 600VAC/300VDC

The Mersen A6T10 is a Class T fast-acting fuse from the Amp-Trap® line, engineered to combine high current-limitation with a compact physical size for demanding AC/DC power protection applications. Rated 600VAC and 300VDC with an AC maximum interrupting rating (I1) of 200 kA, this fuse operates at 50/60 Hz and is built with a durable glass melamine (GMG) body for superior dimensional stability. The A6T10 is available with a choice of connection type — Blade or Ferrule — letting engineers and contractors match the fuse to the physical configuration of their disconnect, panelboard, or fusible enclosure without sacrificing performance. Regardless of connection type selected, the shared 600VAC/300VDC dual voltage rating, 200 kA interrupting capacity, and GMG body construction remain constant across the family. Unique physical dimensions on every A6T10 fuse prevent substitution of fuses carrying lower voltage ratings or reduced current-limiting capability, protecting the integrity of the circuit design. The A6T10 is RoHS compliant, making it suitable for environmentally conscious commercial and industrial installations that require dependable, code-compliant overcurrent protection.

Key Features
