The Eaton Cutler-Hammer FRS-R-4 fuse is a compact yet robust protective device that weighs in at only 0.13 pounds. It possesses a 4A current rating and can operate securely under AC conditions up to 600 volts and DC conditions up to 300 volts, making it versatile across multiple setups. This fuse falls into the Class RK5 category, designed for general-purpose use while providing enhanced overload protection.
With an impressive AC interrupting rating of 200 kA RMS symmetrical at 600 volts, the FRS-R-4 is crafted to handle significant fault currents without compromising the integrity of the circuit. Additionally, it can manage a DC interrupting rating of 20 kA at 300 volts, enabling it to safeguard systems effectively under various electrical configurations.
The time-delay response of this fuse allows it to tolerate inrush currents, delivering a time delay of a minimum of 10 seconds when exposed to 500% of its rated current, which is crucial for maintaining circuit stability during transient conditions. Its dual-element construction adds an extra layer of reliability to its operation.
Connection of the FRS-R-4 is achieved through ferrule end fittings, ensuring straightforward installation without the need for complex modifications. It should be noted that this fuse is non-indicating, which means it does not provide a visual signal to indicate blown status, ensuring a clear understanding of when replacement is necessary.
