Why Choose the Mersen ATDR1-1/8 Class CC Fuse?
The Mersen ATDR1-1/8 is a premium 1.125 A Class CC time-delay fuse designed to provide dependable overcurrent and short-circuit protection for industrial control circuits, small motors and branch circuits. As part of the trusted Mersen Amp-Trap 2000 ATDR series, it delivers excellent current-limiting performance while allowing temporary motor-starting and transformer inrush currents without nuisance fuse operation.
Its dual-element time-delay construction provides rapid interruption of sustained overloads and fault currents while tolerating harmless temporary current surges. The compact Class CC rejection-style design helps maximise panel space and prevents incorrect fuse replacement when installed in compatible Class CC fuse holders.
With a rated current of 1.125 A and voltage ratings of 600 V AC and 300 V DC, the ATDR1-1/8 is ideally suited for industrial automation systems, control panels, transformers, contactors and other low-current branch circuit applications requiring reliable protection.
