FAQs
The RES-30 is a 30 A, 600 V, 10 kAIC time-delay fuse with ferrule ends, ideal for motor control circuits, lighting feeders, and distribution panels in industrial and commercial structures. Its time-lag design tolerates short surges, enabling selective coordination with upstream protection and reducing nuisance trips.
Time-lag (super lag) delays fuse clearing during brief inrush events common with motors, preventing unnecessary outages while still protecting against sustained faults. This improves equipment uptime and extends motor life by avoiding excessive voltage dips and unnecessary replacements.
Yes. The RES-30 uses ferrule end x ferrule end terminations and is designed to fit standard Bussmann series mounting arrangements, enabling straightforward replacement in existing panels and minimizing installation time.
Plan for a fuse that is 5 inches long with a 0.81 inch width and height, weighing about 0.18 lb. Use in circuits up to 600 V with a 10 kAIC interrupt rating at 250 Vac, and ensure ferrule crimp leads are properly installed for reliable, vibration-resistant connections in panels.
The RES-30 offers 10 kAIC interrupt rating at 250 Vac, indicating it can safely interrupt high fault currents in typical commercial and industrial circuits, protecting conductors and equipment while meeting short-circuit withstand requirements.
