Why Choose the Mersen ATQR2/10 Class CC Fuse?
The Mersen ATQR2/10 is a compact, high-performance Class CC time-delay fuse engineered to provide dependable overcurrent protection for industrial control transformers, relays, solenoids and other inductive loads. As part of the renowned Mersen Amp-Trap® 2000 ATQR series, it combines advanced current-limiting protection with a time-delay characteristic that withstands normal equipment inrush currents while rapidly clearing fault conditions.
Designed specifically for branch circuit protection in industrial control systems, the ATQR2/10 helps minimise nuisance fuse operation during transformer energisation while protecting valuable electrical equipment against overloads and short circuits. Its rejection-style Class CC construction also helps prevent the installation of incompatible replacement fuses when used with the appropriate fuse holder.
With a rated current of 0.2 A, a maximum AC voltage rating of 600 V and a DC voltage rating of 300 V, the Mersen ATQR2/10 is ideally suited to sensitive industrial control circuits where reliable low-current protection is essential.

Reliable Protection for Industrial Control Systems
The Mersen ATQR2/10 is designed to protect low-current industrial control circuits where reliability is essential. Its time-delay performance allows normal transformer magnetising current and equipment start-up surges to pass without nuisance operation while still providing rapid interruption of sustained overloads and short circuits.
Its current-limiting design reduces thermal and mechanical stress during fault conditions, helping protect sensitive control equipment, reduce downtime and improve the long-term reliability of industrial electrical systems.
Typical Applications
- Industrial control transformers.
- Control panels and switchboards.
- Relays, solenoids and contactors.
- PLC and automation control circuits.
- OEM machinery.
- Industrial automation equipment.
