Why Choose the Mersen ATQR2 Class CC Fuse?
The Mersen ATQR2 is a compact and reliable Class CC time-delay fuse designed to protect industrial control transformers, solenoids, contactors, relays and other inductive electrical loads. As part of the proven Mersen Amp-Trap® 2000 ATQR series, it combines dependable current-limiting protection with the ability to tolerate temporary inrush currents during transformer energisation and equipment start-up.
Its time-delay operating characteristic helps prevent unnecessary fuse operation under normal start-up conditions while providing rapid interruption of sustained overloads and damaging short circuits. The Class CC rejection-style construction also helps prevent incompatible fuse types from being installed when the ATQR2 is used with a suitable rejection fuse holder.
With a rated current of 2 A, an AC voltage rating of 600 V and a DC voltage rating of up to 300 V, the ATQR2 is well suited to industrial control panels, machinery and automation systems. Its compact cylindrical format supports space-efficient installation, while its high interrupting capacity provides dependable protection in demanding electrical environments.

Reliable Protection for Transformers and Control Circuits
Control transformers and inductive components can draw a temporary surge of current when first energised. The Mersen ATQR2 is designed to tolerate these normal inrush currents, helping reduce nuisance fuse operation while maintaining effective protection against sustained overloads and short circuits.
During a high-level electrical fault, the fuse’s current-limiting construction restricts the peak current and energy passing through the circuit. This helps protect transformers, conductors, contactors and downstream control equipment while reducing the risk of extensive damage and unplanned production downtime.
Typical Applications
- Industrial control transformers.
- Solenoids, relays and contactors.
- Motor control centres and electrical panels.
- Machine tools and automated production machinery.
- Heating, ventilation and air-conditioning control circuits.
- OEM machinery and industrial automation systems.
