ATQR6 – GOULD 6A 600V CLASS CC TIME DELAY FUSE

The ATQR series is a time-delay (dual-element) Class CC fuse, meaning it tolerates brief inrush currents — such as motor starting surges — without nuisance blowing, while still providing fast, reliable protection against sustained overloads and short circuits. A standard (fast-acting) Class CC fuse would not offer this inrush tolerance and may trip unnecessarily in those applications.

Yes — provided the replacement is a Class CC time-delay fuse rated 6A and 600V with an equal or greater interrupting rating (200kA). Common cross-references include the Bussmann FNQ-R-6 and Littelfuse CCMR6. Always confirm the replacement meets your specific circuit's requirements and is approved for use in Canada (CSA-listed).

Gould's fuse lines were acquired by Ferraz Shawmut (now Mersen), and some legacy ATQR catalogue numbers may be limited in availability.
