The ATQR1/4 is a time-delay Class CC fuse specifically designed to handle high inrush currents from inductive loads. It carries a rating of 1/4A and 600VAC with an interrupting capacity of 200kA AC. The fuse's time-delay characteristic prevents nuisance opening with control transformers and solenoids, while its current-limiting capability ensures low peak let-thru currents. Built with a durable fiberglass body and high-grade silica filler for fast arc quenching, it offers superior protection. Common applications include control transformers, solenoids, inductive loads, and other general-purpose branch circuits in electrical distribution systems.
