Why Choose the Mersen ATDR1-1/4 Class CC Fuse?
The Mersen ATDR1-1/4 is a premium 1.25 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 combines excellent current-limiting performance with superior time-delay characteristics, allowing temporary motor starting and transformer inrush currents without nuisance fuse operation.
Its dual-element 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 valuable panel space and prevents incorrect fuse replacement when used with compatible Class CC fuse holders.
With a rated current of 1.25 A and voltage ratings of 600 V AC and 300 V DC, the ATDR1-1/4 is ideally suited for industrial control panels, automation equipment, contactors, transformers and branch circuit protection where reliable performance is essential.
