The ATQR3 is a 3A, time-delay Class CC fuse specifically designed to handle the high inrush currents of control transformers, solenoids, and similar inductive loads. It provides superior branch circuit protection with voltage ratings of 600VAC and 300VDC, and features high interrupt ratings of 200kA AC and 100kA DC. The fuse's time-delay characteristic prevents nuisance opening during temporary inrush events without sacrificing protection. Its fiberglass body provides dimensional stability in harsh industrial settings, making it a reliable choice for protecting control transformers, solenoids, and other inductive or general-purpose loads.
