Why Choose the Mersen ATDR2-1/4 Class CC Fuse?
The Mersen ATDR2-1/4 is a premium Class CC time-delay industrial fuse engineered to provide dependable overcurrent and short-circuit protection for branch circuits, motor control systems, transformers and industrial automation equipment. As part of the trusted Mersen Amp-Trap 2000® ATDR series, it delivers outstanding current-limiting performance while allowing temporary inrush currents associated with motors and transformers without nuisance operation.
Designed for demanding industrial environments, the ATDR2-1/4 provides superior protection for increasingly sensitive electrical equipment. Its time-delay operating characteristic allows normal equipment start-up while responding rapidly to sustained overloads and fault conditions. The rejection-style Class CC design also helps prevent incorrect fuse replacement when installed in compatible fuse holders.
With a 2.25 A current rating, 600 V AC and 300 V DC voltage ratings, the Mersen ATDR2-1/4 is ideal for industrial control panels, machine tools, OEM equipment and automation systems requiring compact, high-performance branch circuit protection.
