FAQs
NOS-35 fuses use ferrule end connections and measure 5.5 in long by 1.06 in square, which simplifies panel mounting and terminal compatibility. Ensure the holder accepts Class K5/H non-indicating fuses and confirm a suitable 50 kAIC interrupt rating at 600 V for your fault-clearing requirements. The pin-indicating feature helps verify correct installation, while the packaging quantity of ten units supports stocking for repeat replacements.
NOS-35 is rated for 35 A continuous operation with a 600 V voltage rating and a 50 kAIC interrupt rating, enabling it to safely interrupt high fault currents in industrial circuits. It is designed as a non-current-limiting, one-time fuse, suitable for general protection in control panels and motor circuits within EU and global assemblies that require CE Marked compliance.
Yes. The NOS-35 is a general-purpose, non-current-limiting fuse in the Bussmann Class K5/H family, intended for non-resettable protection in common automation applications such as control panels and power distribution paths. Its 35 A rating and 50 kAIC interrupt capability make it appropriate for typical branch circuits while maintaining CE compliance for cross-border projects.
NOS-35 carries CE Marking, indicating compliance with European safety standards for electrical protection devices. It is a Bussmann series Class K5/H fuse, designed for predictable performance in general protection roles. When sourcing for global deployments, verify that your system design aligns with CE requirements and maintain documentation to support cross-border procurement and audits.
NOS-35 is a one-time, non-resetting fuse, which eliminates nuisance resets after fault events and reduces downtime associated with fuse cycling. While unit cost may be higher than a resettable device, the fast fault clearance, straightforward replacement (ten per package) and CE-certified design can lower total downtime costs, improve mean time between failures (MTBF), and simplify asset maintenance planning in automation environments.
