ATQR2 is a time-delay Class CC fuse designed to protect control transformers, solenoids, and inductive loads from fault currents while accommodating high inrush currents without nuisance opening. The fuse is rated at 2A with a voltage rating of 600VAC (or 300VDC for higher amperage variants) and features a 200kA interrupting rating (AC) and 100kA (DC), providing highly current-limiting protection with low peak let-thru current. The fuse body is constructed from fiberglass for dimensional stability in harsh industrial environments, filled with high-grade silica for fast arc quenching and superior current limitation. Its rejection-style design prevents replacement errors when used with recommended fuse blocks, while the metal-embossed date and catalog number ensure traceability. ATQR2 is ideal for branch circuit protection in electrical distribution systems serving lighting, heating, and general-purpose loads, and is UL listed to standard 248-4 and CSA certified.
