The NRN30 – Gould 30A 250V Class H One-Time Fuse is designed for reliable electrical protection in various industrial applications. With a 30 amp rating and a voltage capacity of 250 volts, this fuse ensures safety and efficiency. Ideal for replacing old fuses, it provides essential circuit protection in your setup.
No. The NRN30 is a one-time (non-renewable) Class H fuse — once it operates during a fault or overload, it must be completely replaced. It cannot be rewired, refilled, or reset. Always keep spare fuses on hand for quick replacement.
Yes, in most cases. Class H cartridge fuses are standardized by physical dimension and electrical rating, so the NRN30 (30A, 250V) is generally interchangeable with other manufacturers' Class H or Class K one-time fuses of the same rating. However, always verify your holder's class and voltage markings before substituting. Contact us if you need help cross-referencing.
The Gould NRN series is considered a legacy product line, but Northern Breaker Group specializes in obsolete and hard-to-find electrical components — we can source NRN30 fuses or recommend a compatible current-production equivalent. If your application demands a higher interrupting rating, upgrading to a Class RK5 or RK1 fuse may be worth discussing with our team.
