Mersen A6T Series Class T Fast-Acting Fuse, 600VAC/300VDC

Mersen A6T Series Class T Fast-Acting Fuse, 600VAC/300VDC, Amp-Trap®

The Mersen A6T Series 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. Its unique physical dimensions prevent substitution of fuses carrying lower voltage ratings or reduced current-limiting capability, protecting the integrity of the circuit design. The A6T is RoHS compliant, making it suitable for environmentally conscious commercial and industrial installations that require dependable, code-compliant overcurrent protection.

Key Features

• Voltage Rating: 600VAC / 300VDC for versatile AC and DC circuit protection in a single fuse design.
• Durable Construction: Glass melamine (GMG) body delivers superior dimensional stability for reliable long-term performance in the field.
• Fast-Acting Class T Design: Combines high current-limitation with a small physical size, ideal for space-constrained panelboards, disconnects, and enclosures.
• High Interrupting Capacity: AC maximum interrupting rating (I1) of 200 kA breaking capacity supports demanding fault-current environments.
• Copper Terminals: Copper connection/terminal material supports dependable, low-resistance electrical contact.
• 50/60 Hz Frequency: Compatible with standard AC power systems used throughout commercial and industrial facilities.
