Description

Dual Class RK5 Fuse 70 A, Blade End x Blade End, 600 Vac/300 Vdc, 10 sec Response

Features

This 70-amp Fusetron™ fuse features a sophisticated dual-element design that provides a minimum 10-second time-delay at 500% of the rated load. By distinguishing between temporary harmless inrush currents and actual destructive overloads, it allows heavy-duty industrial motors and transformers to start without interruption, significantly reducing facility downtime and maintenance calls.
Engineered to be highly current-limiting, the FRS-R-70 reacts almost instantaneously to short circuits, restricting the peak let-through current to levels far below the available fault current. This rapid response prevents catastrophic thermal and magnetic stress on your electrical infrastructure, protecting sensitive circuit breakers, contactors, and busbars from permanent damage.
Fully UL Listed and CSA Certified for heavy-duty industrial applications, this 70-amp overcurrent protection device ensures your commercial power distribution systems easily pass rigorous local safety inspections. Trusting factory-tested, industry-standard hardware guarantees maximum reliability for your main service panels and transformers, ensuring your facility operations remain entirely code-compliant and your liability insurance remains valid.
