Why Choose the Mersen ATDR25 Class CC Fuse?
The Mersen ATDR25 is a compact and reliable Class CC time-delay industrial fuse designed to protect motor circuits, transformers, control equipment and industrial machinery against overloads and short-circuit faults. As part of the established Mersen Amp-Trap 2000® ATDR series, it combines effective current-limiting protection with the ability to tolerate temporary start-up currents.
The ATDR25 is engineered for circuits containing motors, transformers, solenoids and other inductive loads that can draw substantial inrush current when energised. Its time-delay operating characteristic helps prevent unnecessary fuse operation during normal equipment start-up while maintaining dependable protection against sustained overloads and severe fault currents.
With a rated current of 25 A, an AC voltage rating of 600 V and a DC voltage rating of 300 V, the ATDR25 is suitable for demanding industrial power and control applications. Its rejection-style Class CC construction allows installation in compatible fuse holders while helping prevent replacement with an unsuitable fuse class.

Reliable Protection for Motors and Industrial Equipment
Time-delay fuses such as the Mersen ATDR25 allow temporary inrush currents to pass without unnecessarily interrupting the circuit. This is particularly important for motors, transformers and electromagnetic equipment that can draw several times their normal operating current during start-up.
During a short circuit, the ATDR25 provides current-limiting operation that helps reduce the peak current and electrical energy reaching downstream equipment. This can minimise thermal and mechanical stress on conductors, contactors, motor controllers and other valuable industrial components.
Typical Applications
- Industrial motor branch circuits.
- Control transformers and power supplies.
- Motor control centres and electrical panels.
- Industrial machinery and production equipment.
- Heating, ventilation and air-conditioning systems.
- OEM automation and machine-building applications.
