The ATQR2 – Gould 2A 600V Class CC Time Delay Fuse is designed to provide reliable protection for your electrical circuits. Featuring a time delay characteristic, this fuse allows for brief overload conditions without blowing, ensuring smooth operation. Ideal for a variety of applications, it guarantees safety and durability in demanding environments.
The ATQR2's time-delay design allows it to tolerate brief, harmless overload surges — such as motor inrush currents or transformer energizing peaks — without nuisance blowing. It still responds quickly to sustained overloads and short-circuit faults, providing dependable protection without unnecessary downtime.
Gould's fuse lines were acquired by Ferraz Shawmut and later Mersen, so the ATQR2 designation may appear under different branding. Functionally identical Class CC 2A 600V time-delay replacements are available from Bussmann (ATQR2) and Littelfuse (CCMR2). Northern Breaker Group specializes in obsolete and hard-to-find fuses — contact us and we'll source the right unit for you.
While a fast-acting Class CC fuse will physically fit the same Class CC holder, substituting it for a time-delay fuse is not recommended without an engineering review. Fast-acting fuses will not ride through normal inrush currents and may cause nuisance tripping. Always match the fuse type (time-delay vs. fast-acting) to the original specification for your equipment.
