Why Choose the Mersen ATQR30 Class CC Fuse?
The Mersen ATQR30 is a compact Class CC time-delay fuse designed to provide dependable overcurrent protection for control transformers, solenoids and similar inductive loads. Part of the Mersen Amp-Trap® 2000 ATQR series, it combines time-delay operation with high current-limiting performance for branch circuits in industrial electrical distribution systems.
Its time-delay characteristic accommodates the temporary inrush currents produced when transformers and inductive equipment are energised, helping to minimise nuisance fuse operation. During sustained overloads or short circuits, the ATQR30 responds to protect conductors, switching devices and downstream equipment from potentially damaging fault current.
Rated at 30 A, 600 V AC and 300 V DC, the ATQR30 is suitable for industrial control panels, machinery and electrical distribution applications requiring a compact fuse with a high interrupting capacity. Its Class CC rejection-style format also helps prevent the installation of incompatible fuse types when used with an appropriate holder.

Time-Delay Protection for Inductive Loads
Control transformers, solenoids and other inductive devices can draw a substantial temporary surge of current when energised. The Mersen ATQR30 is engineered to tolerate this normal inrush without operating unnecessarily, while continuing to provide effective protection against abnormal overcurrent conditions.
Its current-limiting design restricts the peak current and energy passed during a high-level fault. This can reduce thermal and mechanical stress on conductors, transformers, contactors and other circuit components, helping to improve equipment reliability and minimise disruption.
Typical Applications
- Industrial control transformers.
- Solenoids, contactors and relays.
- Industrial control panels.
- Motor control centres.
- Electrical distribution branch circuits.
- Automated machinery and production equipment.
- OEM control and power systems.
