Bussmann Fusetron FRN-R Series Dual-Element Fuse, 250V

Bussmann Fusetron FRN-R Series Dual-Element Fuse, 250V

The Bussmann Fusetron FRN-R Series is a family of dual-element, time-delay fuses rated 250V, offered across a range of amperage ratings including 2.25 Amp, 2.5 Amp, 3.5 Amp, and 6.25 Amp so the correct current rating can be selected for the specific circuit being protected. Manufactured by Bussmann under the Fusetron designation, these fuses are built to protect wiring, equipment, and connected loads by interrupting current flow when a fault or overload condition develops. Each fuse in the FRN-R Series shares the same 250V voltage rating and Fusetron form factor, with the amperage rating selected at time of order to match the exact requirement of the fuse holder or equipment being serviced. This series is intended as a direct replacement for applications and fuse holders originally designed around the Bussmann FRN-R model number, voltage rating, and the specific amperage called for by the equipment nameplate.

Key Features

• Amperage Rating Range: Available in 2.25 Amp, 2.5 Amp, 3.5 Amp, and 6.25 Amp ratings to match the exact current requirement of the circuit.
• Voltage Rating: Rated 250V per the Fusetron 250V manufacturer designator, suitable for circuits operating at or below this voltage.
• Fusetron Series: Part of the Bussmann Fusetron FRN-R fuse line, a dual-element, time-delay fuse family.
• Bussmann Manufactured: Produced by Bussmann, a manufacturer of circuit protection components for electrical distribution systems.
• Exact Model Match: Sized and rated to match the FRN-R designation for use where this specific Bussmann Fusetron series is specified by equipment or panel manufacturers.
• Replacement Part: Suited for use as a direct replacement in fuse holders and panelboards designed for the FRN-R rating and form factor.
• Form Factor: Physical size and mounting are consistent across the FRN-R series for compatibility with fuse holders designed for this Bussmann Fusetron model line.

Technical Specifications

• Amperage Rating: 2-1/2A (selectable option; series spans 2.25 Amp to 6.25 Amp)
