Molded in-line fuse protects against ground fault damage

Amphenol Industrial Global Operations now offers the HelioFuse, a molded in-line fuse that helps to protect photovoltaic (PV) systems from ground fault current damage. The new fuse addresses the need for a cost-effective solution to ground fault protection in PV systems without the need for a combiner box that houses the solar panel's fuse links.

The HelioFuse is designed for rapid removal and replacement with minimal system downtime should a ground fault occur. It is fully intermateable with industry standard PV connectors. The IP68-rated HelioFuse is offered in two configurations, a connector version that plugs into an industry standard solar connector like the Helios H4 connector and a wire overmold version for custom harnesses.

The HelioFuse operates at a maximum of 1000 V DC with a 20 A rating and a 10,000 A current withstand rating.
