Galvanic Isolator GI
The philippi Galvanic Isolator GI is a corrosion protection component that is installed in the shore power connection of boats, between the hull and the shore power grid, to prevent unwanted galvanic currents. It is particularly suitable for yachts with plastic hulls whose propulsion system needs to be protected from galvanic corrosion via the shore power connection.
- Robust design
In detail. Galvanic Isolator GI.
- Protects drive, propeller, and metal parts in the water from electrolysis caused by the shore power connection
- Waterproof potted electronics in an anodized aluminum housing – designed for continuous use on board
- Two versions for 16 A or 32 A circuit protection – suitable for different shore power capacities
The philippi Galvanic Isolator is integrated into the protective earth (PE) conductor of the shore power connection. Two diodes, connected in anti-parallel and in series, create such a high blocking potential that galvanic currents can no longer flow between the hull and the shore power grid, while fault current protection via the protective earth conductor is maintained. For GRP hulls, the galvanic isolator thus separates the hull from the shore power potential and prevents corrosion of metallic components that can arise due to different electrochemical potentials between the hull, the shore connection, and neighboring metal objects (e.g., steel sheet piles).

Frequently asked questions. Answered briefly.
Where is the Galvanic Isolator GI installed?
It is integrated into the protective earth (PE) conductor of the shore power connection on boats, between the hull and the shore power grid, to prevent unwanted galvanic currents.
Is the Galvanic Isolator GI also useful for plastic hull yachts?
Yes, it is specifically recommended for yachts with plastic hulls to protect the propulsion unit from galvanic corrosion caused by the shore power connection.
How does the corrosion protection work technically?
Two diodes, connected in anti-parallel and in series, create such a high blocking potential that galvanic currents can no longer flow.
Which version do I need, GI 16 or GI 32?
This depends on the circuit protection of your shore power connection: The GI 16 is designed for 16 A, and the GI 32 for 32 A circuit protection.
Goes well with it. Accessories and add-ons.
