ATQR1 Mersen – Fuse ATQR – Class CC – Time-Delay 600VAC 300VDC 1A Ferrule Amp-Trap 2000®

The Mersen ATQR1 fuse is part of the Amp-Trap 2000® series, specifically engineered to provide reliable and long-lasting protection for control circuits, motors, and transformers—especially in demanding industrial environments.

First, thanks to its time-delay function, this Class CC fuse can withstand short-term overcurrents—such as those caused by motor startup—without triggering an unnecessary shutdown. This ensures operational continuity while effectively preventing unplanned downtime.

Next, its compact capsule format allows for quick and easy installation, even in tight control panels or space-constrained enclosures. As a result, it integrates efficiently into a wide range of setups while meeting strict safety standards.

In case of a short circuit, the ATQR1 fuse reacts quickly and accurately, helping to protect your equipment and reduce costly damage, which also helps your electrical system last longer.

Finally, the ATQR1 fuse is known for its reliable performance, long-lasting quality, and easy installation, making it a great choice for industrial systems that need strong equipment protection and continuous operation.
