Why Choose the Mersen ATDR17-1/2 Class CC Fuse?
The Mersen ATDR17-1/2 is a premium 17.5 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 trusted Mersen Amp-Trap 2000 ATDR series, it delivers exceptional current-limiting performance while accommodating temporary motor-starting and transformer inrush currents without nuisance operation.
Its dual-element time-delay construction provides superior protection for sensitive electrical equipment while allowing normal operating surges to pass uninterrupted. The compact Class CC rejection-style design helps maximise panel space and prevents incorrect fuse replacement when used with compatible Class CC fuse holders.
Rated at 17.5 A with voltage ratings of 600 V AC and 300 V DC, the ATDR17-1/2 is ideal for industrial automation systems, OEM machinery, motor branch circuits and electrical control panels requiring reliable, high-performance circuit protection.
