Why Choose the Mersen ATDR2-1/2 Class CC Fuse?
The Mersen ATDR2-1/2 is a premium Class CC time-delay industrial fuse designed to provide reliable overcurrent and short-circuit protection for branch circuits, motor control systems, transformers and industrial automation equipment. As part of the renowned Mersen Amp-Trap 2000® ATDR series, it delivers exceptional current-limiting performance while allowing temporary inrush currents associated with motors and transformers.
Designed for demanding industrial environments, the ATDR2-1/2 helps minimise nuisance fuse operation during equipment start-up while responding rapidly to sustained overloads and fault conditions. Its rejection-style Class CC design also prevents incorrect fuse replacement when used with compatible fuse holders, improving electrical safety and system reliability.
With a 2.5 A current rating, 600 V AC and 300 V DC voltage ratings, the Mersen ATDR2-1/2 is ideal for protecting industrial control panels, machine tools, OEM equipment and automation systems where dependable branch circuit protection is essential.
