Why Choose the Mersen ATQR3/10 Class CC Fuse?
The Mersen ATQR3/10 is a compact Class CC time-delay fuse engineered to provide reliable overcurrent protection for industrial control transformers, solenoids, relays and other inductive electrical loads. As part of the proven Mersen Amp-Trap® 2000 ATQR series, it combines superior current-limiting performance with a time-delay characteristic that withstands the high inrush currents associated with transformer energisation and equipment start-up.
Its time-delay operating characteristic helps minimise nuisance fuse operation during normal equipment start-up while providing rapid interruption of sustained overloads and short circuits. The rejection-style Class CC construction also helps prevent incompatible fuse types from being installed when used with a compatible Class CC fuse holder.
With a rated current of 0.3 A, an AC voltage rating of 600 V and a DC voltage rating of 300 V, the ATQR3/10 is ideal for protecting sensitive industrial control circuits, automation equipment and branch circuits where precise low-current protection is required.

Reliable Protection for Sensitive Industrial Control Systems
The Mersen ATQR3/10 is specifically designed to protect sensitive industrial control transformers and low-current inductive equipment. Its time-delay characteristic allows normal transformer magnetising current and equipment start-up surges to pass without nuisance operation while maintaining dependable protection against sustained overloads and short circuits.
Its advanced current-limiting construction reduces thermal and mechanical stress during electrical faults, helping protect valuable control equipment, minimise downtime and improve the long-term reliability of industrial automation systems.
