The OTN15 – Gould 15A 250V Class K5 One-Time Fuse is designed for reliable overload protection in various applications. With its robust construction, this fuse ensures durability and safety, making it ideal for both residential and commercial use. Trust this high-quality fuse to effectively safeguard your electrical systems.
A one-time fuse like the Gould OTN15 is a non-renewable type — once it blows, it must be replaced entirely. Renewable fuses allow the internal element to be replaced in the field, but one-time fuses are generally more consistent and cost-effective for permanent installations. You can upgrade to a time-delay (dual-element) Class K5 or Class RK5 fuse if your application involves motor loads or inrush currents, but always verify the holder is rated for the replacement class. Contact us and we can help you identify the right fuse type for your load.
The Gould OTN (one-time) series has been produced under various brand names over the years, including Gould Shawmut and later Mersen. Northern Breaker Group specializes in obsolete and hard-to-find electrical components, so we can source OTN15 stock or provide a verified cross-reference such as the Bussmann NON-15 or equivalent 15A 250V Class K5 one-time fuse. Reach out to our Calgary, Edmonton, or Vancouver locations for current availability.
The Gould OTN15 is a general-purpose Class K5 one-time fuse rated for 15A at 250V AC with a 50kA interrupting rating, suitable for overload and short-circuit protection in residential, commercial, and light industrial branch circuits. However, because it has no built-in time-delay, it is not the ideal choice for motor branch circuits where high inrush currents at start-up can cause nuisance blowing. For motor loads, a dual-element time-delay fuse (such as a Class K5 or RK5 TD type) is generally recommended. Contact us if you need guidance on the correct fuse for your specific application.
