Why Choose the Mersen ATQR1-8/10 Class CC Fuse?
The Mersen ATQR1-8/10 is a premium Class CC time-delay fuse designed to provide dependable overcurrent protection for industrial control transformers, solenoids, relays and other inductive electrical loads. As part of the trusted Mersen Amp-Trap® 2000 ATQR series, it combines advanced current-limiting technology with the ability to withstand the high inrush currents commonly experienced during transformer energisation and equipment start-up.
Its time-delay operating characteristic helps eliminate nuisance fuse operation during normal energisation while rapidly interrupting overloads and short circuits. The rejection-style Class CC construction also helps prevent the installation of incorrect replacement fuses when used with compatible Class CC fuse holders, improving system safety and reliability.
With a rated current of 1.8 A, a maximum voltage rating of 600 V AC and a 300 V DC rating, the ATQR1-8/10 is ideally suited to industrial control panels, machinery and automation systems requiring dependable branch circuit protection.
