Bussmann FRN-R-5 Dual Class RK5 Fuse, 5 A, Ferrule End x Ferrule End, 250 Vac, 125 Vdc, 20 kAIC

Description

Features

• The advanced dual-element design provides a minimum of 8 seconds of time-delay at 500% of the 5-amp rated current. This allows your machinery and motors to draw necessary temporary surge currents during startup without nuisance tripping, preventing costly downtime and unnecessary maintenance cycles.
• Engineered with an exceptional interrupting rating of 200 kA RMS Symmetrical at 250 Vac (and 20 kA at 125 Vdc), this current-limiting fuse safely clears high-energy faults. It stops dangerous short-circuit currents before they can damage downstream equipment or compromise your industrial panelboard safety.
• The precise low-level overload element delivers dedicated protection that prevents motor burnouts caused by overloads or single-phasing on three-phase electrical systems. It acts as a reliable safeguard for expensive industrial motors, reducing replacement costs and keeping your production line operational.
