Why Choose the Mersen ATDR7 Class CC Fuse?
The Mersen ATDR7 is a compact and dependable Class CC time-delay industrial fuse designed to protect motors, transformers, control equipment and industrial branch circuits 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 withstand temporary equipment start-up currents.
The ATDR7 is particularly suitable for circuits containing motors, control transformers, solenoids, contactors and other inductive loads that can draw elevated current when energised. Its time-delay operating characteristic helps prevent unnecessary fuse operation during normal start-up while maintaining dependable protection against sustained overloads and high-level fault currents.
With a rated current of 7 A, an AC voltage rating of 600 V and a DC voltage rating of 300 V, the ATDR7 is suitable for industrial control panels, automated machinery and OEM equipment. Its rejection-style Class CC construction enables installation in compatible fuse holders while helping prevent replacement with an unsuitable fuse type.
Key Advantages
- Compact Class CC time-delay fuse for industrial circuit protection.
- 7 A current rating suitable for control, transformer and motor circuits.
- 600 V AC and 300 V DC voltage ratings.
- Time-delay performance accommodates temporary equipment inrush currents.
- Current-limiting operation helps reduce damaging fault energy.
- Rejection-style construction supports correct fuse selection and installation.
Key Features
- Mersen Amp-Trap 2000® ATDR fuse series.
- 7 A rated current.
- 600 V AC rated voltage.
- 300 V DC rated voltage.
- Class CC time-delay current-limiting fuse.
- High interrupting capacity for demanding industrial fault conditions.

Reliable Protection for Industrial Electrical Systems
Time-delay fuses such as the Mersen ATDR7 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 or energisation.
During a short circuit, the ATDR7 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, control components and other valuable industrial devices.
Typical Applications
- Industrial control panels.
- Motor branch and control circuits.
- Control transformers and power supplies.
- Programmable logic controller systems.
- OEM machinery and automation equipment.
- Contactors, relays and solenoid circuits.
