Why Choose the Mersen ATQR4/10 Class CC Time-Delay Fuse?
The Mersen ATQR4/10 is a premium Class CC time-delay fuse designed to provide dependable branch circuit protection for industrial electrical systems. As part of the trusted Mersen Amp-Trap 2000® ATQR series, it is specifically engineered to withstand the high inrush currents associated with control transformers, solenoids and similar inductive loads while delivering outstanding current-limiting performance during fault conditions.
Its advanced time-delay characteristic helps prevent nuisance fuse operation during equipment start-up while maintaining rapid interruption of overloads and short circuits. The compact Class CC design makes it ideal for modern industrial control panels where space is limited but reliable overcurrent protection is essential.
With a 0.4 A current rating, 600 V AC / 300 V DC voltage rating and high interrupting capacity, the ATQR4/10 is an excellent choice for protecting sensitive industrial control circuits, automation equipment and OEM machinery.
