Why Choose the Mersen ATQR3 Class CC Fuse?
The Mersen ATQR3 is a compact Class CC time-delay fuse designed to provide dependable overcurrent protection for control transformers, solenoids and similar inductive electrical loads. Part of the proven Mersen Amp-Trap® 2000 ATQR series, it combines current-limiting performance with the ability to withstand the temporary inrush currents that occur during transformer energisation and equipment start-up.
Its time-delay operating characteristic helps reduce nuisance fuse operation under normal inrush conditions while providing rapid protection against sustained overloads and damaging short circuits. The Class CC rejection-style format also helps prevent incompatible fuse types from being installed when the ATQR3 is used with a suitable Class CC fuse holder.
Rated at 3 A, 600 V AC and 300 V DC, the ATQR3 is suitable for industrial control panels, machinery and branch circuits within electrical distribution systems. Its compact cylindrical ferrule construction supports space-efficient installation, while its high interrupting capacity makes it suitable for demanding industrial environments.

Reliable Protection for Control Transformers and Inductive Loads
Control transformers, solenoids and other inductive components can draw a temporary surge of current when first energised. The Mersen ATQR3 is designed to tolerate these normal inrush conditions, helping prevent unnecessary fuse operation while maintaining dependable protection against sustained overcurrents and short circuits.
During a high-level fault, the fuse limits the peak current and energy passing through the circuit. This helps reduce thermal and mechanical stress on transformers, conductors, switching devices and downstream control equipment, supporting improved system reliability and reduced downtime.
Typical Applications
- Industrial control transformers.
- Solenoids, relays and contactors.
- Control panels and switchboards.
- Motor control centres.
- Machine tools and automated machinery.
- Branch circuits in electrical distribution systems.
- OEM equipment and industrial automation systems.
