The GOUA3T200 is a reliable Gould 200A 300V Class T fast-acting fuse, designed to protect electrical circuits from overloads and short circuits. With its quick response time, this fuse ensures optimal safety for your equipment. Ideal for residential and industrial applications, it guarantees peace of mind while operating your systems.
Yes — Class T fuses are standardized to ANSI/UL dimensions, so the GOUA3T200 (Gould) is dimensionally interchangeable with equivalents such as the Mersen/Ferraz Shawmut A3T200, Bussmann JJN-200, and Littelfuse KLNR-200, provided the voltage rating (300V) and amperage (200A) match your application. Always verify your holder is rated for Class T 200A 300V before substituting.
No — the GOUA3T200 is rated for 300V AC maximum. For 600V applications you would need a 600V-rated Class T fuse (e.g., a Gould A6T200 or equivalent). Using an under-rated fuse on a higher-voltage circuit is a safety and code violation. Contact us and we can help source the correct voltage class.
Generally, no. Fast-acting Class T fuses like the GOUA3T200 are not designed to ride through the inrush current of motor starts, and substituting one for a time-delay fuse in a motor circuit can result in nuisance blowing. If your application involves motors or other high-inrush loads, a time-delay Class T fuse or a different fuse class may be required. Let us know your application and we'll help you select the right type.
