Non-current-limiting design helps avoid nuisance faulting in non-inrush service, enabling smoother startup and less unnecessary downtime. This translates to lower maintenance costs and higher line availability in control cabinets and small motor circuits. The 50 kAIC interrupt rating at 125 Vdc and 250 Vac provides robust short-circuit protection, minimizing equipment damage during faults and reducing downstream downtime. The 30 A rating with a compact 2 in length and ferrule-end connections enables easy retrofit into existing panels and straightforward wiring, improving installation speed and reliability. The Class H designation and CE compliance support safety standards and regulatory alignment across global deployments. Standard packaging of 10 units per box simplifies stocking and maintenance planning, reducing inventory overhead and facilitating quick replacements in field service. As part of the Bussmann series, this fuse integrates smoothly with typical Class H protection blocks, offering consistent protection across multiple devices and panels.

FAQs
Choose the ferrule-end variant with a 2 inch length and 0.56 inch width to fit common panel cutouts. Verify compatible fuse blocks that accept ferrule-end devices and crimp ferrules per manufacturer guidelines to ensure reliable contact. Use the standard packaging of ten units per box for predictable stocking, and follow torque specs to avoid ferrule damage or loose connections that could compromise trips.
NON-30 is a 30 A, non-current-limiting fuse with a 50 kAIC interrupt rating at 125 Vdc and 50 kAIC at 250 Vac. It carries a voltage rating of 250 Vac / 125 Vdc and uses ferrule-end terminations. The device is classified as Class H and provides non-indicating operation, which helps fit into standardized protection schemes in Bussmann series installations.
Yes. The NON-30 fuse is CE marked, indicating conformity with European safety standards. It is designed for general purpose protection in industrial controls and is compatible with Bussmann Series Class H fuses. For European installations, CE marking supports regulatory acceptance and streamlined certification processes.
By delivering non-current-limiting protection in appropriate circuits, the NON-30 minimizes nuisance tripping during startup and reduces unnecessary maintenance. Its robust 50 kAIC interrupt rating protects downstream equipment, lowering repair costs after faults. Easy installation with ferrule ends and standard packaging improves spare-part availability, reducing downtime and inventory overhead, which translates to measurable savings in plant uptime and maintenance spend.
As part of the Bussmann Series Class H fuses, NON-30 is designed for general protection in electrical protection and circuit control. It fits common Bussmann Class H fuse blocks with ferrule-end terminations and is suitable for control panels, motor control centers, and protection cabinets. Its 30 A rating and CE marking support reliable operation across industrial environments and varied voltage levels.
