RACPRO1-4SP e-Fuse Series

The RACPRO1-4SP series are 4-channel electronic fuse (e-Fuse) load switches designed to provide independent overcurrent protection for each channel. They feature real-time current monitoring and LED status indicators to simplify diagnostics. Each channel operates independently, ensuring system reliability even when faults occur. The design includes sequential power-up to limit inrush current and reverse-sequence shutdown to prioritize essential loads. Adjustable overload modes allow flexible system configuration.

These e-Fuses support 5A or 10A per channel, with a 150% power boost for up to 5s to handle temporary load surges. For short-duration overcurrent events, the device can sustain more than 150% overload for up to 120ms, reducing unnecessary tripping.

Built to LPS installation standards, they offer high reliability with a >80,000h lifetime expectancy at 40°C. Installation is streamlined with tool-free push-in terminals and paired input/output connectors, making wiring and daisy-chaining across multiple modules quick and efficient.
