Description

Class RK5 Dual Fuse 20 A, 8 sec at 500%, Non-indicating, 250 Vac, 125 Vdc

Features

Engineered with a sophisticated dual-element design, the FRN-R-20 provides a minimum 8-second time-delay at 500% of its rated current. This allows it to hold momentary surges from motor startups and inductive loads without "nuisance tripping," while still providing high-speed response to dangerous short circuits.
As a Class RK5 current-limiting fuse, the FRN-R-20 offers superior protection levels with a massive 200kA interrupting rating. This advanced protection significantly reduces the let-through energy during a fault, shielding your downstream branch circuit components and sensitive motor controllers from catastrophic damage.
The Fusetron™ technology is specifically optimized to help protect motors against burnout caused by single-phasing or prolonged overloads. By coordinating the overload and short-circuit elements, it ensures that your industrial equipment stays operational longer while maintaining a strict safety ceiling.
Designed for high-conductivity and low-watt loss, the FRN-R-20 runs cooler than standard fuses in power panelboards and motor control centers. This energy-efficient operation minimizes heat buildup within enclosures, extending the life of adjacent electrical components and improving overall system reliability.
