NewMar GI-60-FS Galvanic Isolator 60A Fail Safe Marine AC Ground Protection

The NewMar GI-60-FS Galvanic Isolator provides essential corrosion protection for marine electrical systems by blocking low-voltage DC currents while maintaining the critical AC safety ground connection. Designed to meet the latest ABYC A-28 2019 requirements, this 60-amp fail-safe unit installs between the AC safety ground and DC bonding system to prevent galvanic corrosion on underwater metallic components in saltwater environments.

How It Works:

By blocking low-voltage stray currents that cause galvanic corrosion, the GI-60-FS significantly extends the life of sacrificial zinc anodes and reduces corrosion on through-hulls, propellers, shafts, and other submerged metals. This translates to substantial savings in haul-out costs and anode replacement expenses. The unit features a large capacitor that provides a secondary low-impedance path for AC fault current to reach ground, ensuring electrical safety is never compromised.
