GI-30-FS Galvanic Isolator 30A Fail Safe

Installing the Galvanic Isolator between the AC safety ground and DC bonding system blocks most of the low-voltage currents and corrosive action seen on the vital metallic components in the saltwater. With the low voltage current blocked, the galvanic corrosion effect on the sacrificial anodes is significantly reduced, while the integrity of the critical safety ground path is maintained. This means a significant saving in boat haul-out fees and zinc replacement costs. For additional safety, all units feature a large capacitor, providing a secondary low-impedance path for sending AC current to the ground.

Newmar’s latest galvanic isolator meets the latest ABYC A-28 2019 requirements, including being a failsafe. This design can meet the strictest temperature and current tests to create a robust solution for galvanic protection.
