Newmar GI-30-FS 30AGalvanic Isolator with Fail Safe

The Newmar GI-30-FS 30A Galvanic Isolator with Fail Safe is designed specifically for marine applications, including cruisers, sailboats, and yachts. It addresses the risks of galvanic corrosion that can damage hulls and through-hull fittings due to stray electrical currents. This product is essential for any captain looking to protect their vessel from the silent threats posed by electrical systems.

Utilizing transformer-based technology, the GI-30-FS effectively isolates the shore power ground from the boat's bonding system. This design prevents destructive current flow while ensuring electrical safety. The unit is certified to the UL1500 standard for Ignition Protection, meeting rigorous marine electrical codes and supporting the full 30-amp service typical of cruising-class vessels.

The fail-safe feature of this isolator is particularly beneficial for owners of aluminum-hulled vessels and those who frequently navigate between marinas with varying electrical infrastructures. In the event of a transformer fault, the device automatically reverts to a grounded state, ensuring continued protection for the bonding system. This critical safeguard helps maintain the integrity of the vessel's electrical system during unforeseen electrical faults.
