Description
Features
- Engineered with a smart dual-element architecture, the FRN-R-50 handles harmless, temporary inrush currents and surges by holding an overload five times its rating for a minimum of 10 seconds. This advanced configuration actively eliminates frustrating nuisance tripping during heavy machinery or HVAC system startups while ensuring dependable overcurrent protection when actual faults happen.
- Boasting an impressive 200 kAIC interrupting rating at 250 VAC, this current-limiting Fusetron™ fuse cuts off massive fault currents before they can damage downstream infrastructure. By rapidly restricting destructive peak thermal and magnetic energy, it acts as a critical line of defense for your electrical service panelboards, motor control centers, and safety switches.
- Measuring a precise 0.81-inch diameter by 3 inches in length with ferrule terminals, this Class RK5 cartridge fuse features a standardized physical footprint. The specialized rejection slot profile prevents the dangerous accidental installation of lower-rated, non-current-limiting Class H or K fuses, ensuring your facility remains strictly code-compliant.
- esigned for highly effective selective coordination within the Bussmann RK5 family, a simple 2:1 amp ratio prevents an isolated electrical fault from traveling upstream. This targeted protection isolates overcurrent disruptions strictly to the affected branch circuit, maximizing total plant uptime and safeguarding nearby electronic components from abrupt power interruptions.
