FRS-R-40 Overview

This fuse features a 200kA@600V AIC rating, ensuring exceptional performance under high fault conditions. The dual element design provides superior time-delay characteristics, allowing for the accommodation of temporary inrush currents without opening, which is crucial for applications involving motors and transformers. Optimized for commercial and industrial environments where system uptime and safety are paramount, the FRS-R-40 enhances protection efficiency and minimizes equipment downtime. Suitable for use in a range of electrical panels and safety interfaces.
