Why Choose the Mersen ATDR12 Class CC Fuse?
The Mersen ATDR12 is a compact 12 A Class CC time-delay fuse designed to provide dependable overload and short-circuit protection for industrial control systems, motors, transformers and branch circuits. As part of the Mersen Amp-Trap 2000 ATDR series, it combines high current-limiting performance with the ability to withstand brief, harmless inrush currents.
Its time-delay operating characteristic helps prevent nuisance fuse operation during motor starting, transformer energisation and other temporary current surges. When a sustained overload or high-level fault occurs, the ATDR12 interrupts the circuit to help protect wiring, control components and connected equipment from thermal and mechanical damage.
With a rated current of 12 A and voltage ratings of up to 600 V AC and 300 V DC, the Mersen ATDR12 is suitable for demanding industrial installations. Its compact rejection-style Class CC construction also helps panel builders conserve enclosure space while maintaining reliable branch-circuit protection.

Reliable Protection for Industrial Electrical Systems
The Mersen ATDR12 protects electrical circuits by interrupting excessive current before conductors and connected equipment sustain serious damage. Its current-limiting construction restricts peak fault current and reduces the total let-through energy during a short circuit, helping protect valuable downstream components.
The fuse's time-delay characteristic allows it to tolerate temporary operating surges without sacrificing protection against sustained overloads. This balance makes the ATDR12 a practical choice for industrial motors, control transformers, automation systems and branch circuits requiring compact, high-performance protection.
Typical Applications
- Small motor branch circuits.
- Industrial control and automation panels.
- Control transformers and power supplies.
- Contactors, relays and solenoid circuits.
- Industrial machinery and processing equipment.
- Heating, lighting and general branch circuits.
