By installing this device in series with the protective earth conductor between the shore supply and the boat's grounding system, you effectively block low-voltage DC galvanic currents that would otherwise flow through the water, causing accelerated corrosion. Unlike generic isolators that may fail under fault conditions, the Victron unit uses robust internal diodes in an anti-parallel configuration, ensuring reliable isolation during normal operation while automatically conducting during AC fault currents to maintain safety.\u003c\/p\u003e\n\u003ch3\u003eHow It Works: Reliable Diode-Based Isolation\u003c\/h3\u003e\n\u003cp\u003eAt the core of the Victron Galvanic Isolator are high-capacity diodes that block DC voltages up to approximately 1.4 V. This threshold is higher than the naturally occurring potential differences between dissimilar underwater metals, effectively stopping corrosive currents. In the event of an AC fault, the diodes conduct, allowing the fault current to flow and trip the upstream residual-current device (RCD) or circuit breaker, ensuring personal safety and compliance with marine electrical standards. The fully potted, waterproof construction (IP67) protects internal electronics from moisture, salt spray, and condensation, making it suitable for installation in engine rooms, lazarettes, and other harsh marine environments.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlocks galvanic corrosion currents\u003c\/strong\u003e – Prevents DC leakage via the shore earth connection, protecting underwater metals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh peak current withstand\u003c\/strong\u003e – Handles transient fault currents up to 6000 A (20 ms), ensuring durability during short circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous current rating\u003c\/strong\u003e – Supports up to 64 A, matching typical shore power demands\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 waterproof and fully potted\u003c\/strong\u003e – Resistant to moisture ingress, ideal for marine and coastal installations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnodised aluminium heat sink\u003c\/strong\u003e – Passive cooling design dissipates heat efficiently, no fans required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple two-stud connection\u003c\/strong\u003e – M6 (approx. 1\/4\") stud terminals for secure, low-resistance wiring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact and robust\u003c\/strong\u003e – Dimensions 63 x 164 x 335 mm, weight 3.2 kg, with integrated mounting slots\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliant with marine standards\u003c\/strong\u003e – Meets relevant safety and EMC requirements for onboard use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose a Victron Galvanic Isolator?\u003c\/h3\u003e\n\u003cp\u003eMany boat owners underestimate the risk of galvanic corrosion until costly damage appears. A shore power connection, while convenient, creates a conductive path between your vessel and neighbouring boats or the marina's metal structures. Without isolation, even small DC voltages can drive destructive currents through the water. The Victron Galvanic Isolator breaks this path for DC while preserving the safety earth for AC faults. Its robust design, with a peak current rating far exceeding typical fault levels, ensures it will not fail when needed most. The anodised aluminium enclosure provides excellent heat dissipation, maintaining performance even under sustained high currents. Installation is straightforward: mount the isolator close to the shore power inlet, connect the shore earth to one stud and the boat's earth to the other, and secure the wiring with appropriate lugs. No ongoing maintenance is required.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThis galvanic isolator is suitable for a wide range of vessels, from small pleasure craft to larger yachts and commercial boats, wherever a shore power connection is used. It is particularly valuable in marinas with high electrical activity, where stray currents are common. Whether you are fitting out a new build or retrofitting an existing electrical system, the Victron Galvanic Isolator provides peace of mind by protecting your investment against hidden corrosion.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNote: For optimal protection, ensure your vessel's anodes are in good condition and regularly inspected. The galvanic isolator works in conjunction with, not as a replacement for, sacrificial anodes.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eSecure Your Vessel's Underwater Metals Today\u003c\/h3\u003e\n\u003cp\u003eDon't let electrolytic corrosion compromise your boat's integrity.
