Why Choose the Mersen ATQR1-1/8 Class CC Fuse?
The Mersen ATQR1-1/8 is a premium Class CC time-delay fuse engineered to provide dependable overcurrent protection for industrial control circuits, transformers, solenoids and other inductive loads. Part of the trusted Mersen ATQR Amp-Trap® 2000 series, it delivers outstanding current-limiting performance while tolerating the high inrush currents commonly experienced during equipment start-up.
Designed for industrial reliability, the ATQR series helps minimise nuisance fuse operations while rapidly interrupting fault currents to protect valuable electrical equipment. Its rejection-style Class CC design also prevents the installation of incorrectly rated fuses when used with compatible Class CC fuse holders, enhancing system safety and compliance.
With a rated current of 1.125 A, a 600 V AC voltage rating and a 300 V DC rating, the Mersen ATQR1-1/8 is ideally suited to industrial control panels, OEM machinery and automation systems where dependable branch circuit protection is essential.
