Bussmann FRS-R-2 Current Limiting Time Delay Fuse

Bussmann FRS-R-2 is a current-limiting time-delay fuse in the RK5 package, engineered to protect electrical circuits by interrupting overcurrent conditions while allowing brief surges to pass untripped. It is rated for 2 A and 600 V, establishing the maximum continuous current and the highest voltage it is designed to safely interrupt. The current-limiting design reduces energy let-through during a fault, helping minimize heat and potential damage to downstream conductors and components. As a time-delay device, the FRS-R-2 is built to tolerate short-duration overcurrents, such as startup transients, without immediate opening in order to prevent nuisance trips in circuits with inductive or surge loads. The RK5 form factor identifies the specific physical packaging and lead configuration used by Bussmann for this series, enabling compatibility with standard connectors, panels, and assemblies in appropriate installations. This Bussmann fuse combines protection performance with a form factor that fits a variety of protective applications where reliable interruption of fault currents is required while accommodating brief transient currents.
