Why Choose the Mersen ATQR4-1/2 Class CC Time-Delay Fuse?
The Mersen ATQR4-1/2 is a premium Class CC time-delay fuse developed 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 generated by control transformers, solenoids and similar inductive loads while delivering exceptional current-limiting protection during overload and short-circuit conditions.
Its advanced time-delay characteristic helps prevent nuisance fuse operation during equipment start-up while ensuring rapid interruption when fault currents occur. The compact Class CC design also enables space-saving installation in industrial control panels, OEM machinery and commercial electrical systems.
With a 4.5 A current rating, 600 V AC / 300 V DC voltage rating and high interrupting capacity, the Mersen ATQR4-1/2 provides reliable protection for sensitive industrial control circuits and electrical distribution equipment.
