{"product_id":"victron-galvanic-isolator","title":"Victron Galvanic Isolator 16A 32A 64A","description":"\u003cp\u003eThe Victron Galvanic Isolator (VDI-16, VDI-32, VDI-64) is a passive shore power earth protection device designed to prevent electrolytic corrosion of a vessel's underwater metals — including the hull, propeller, shaft, and through-hull fittings — caused by low-voltage DC galvanic currents flowing through the shore power earth (PE) wire. Available in three current ratings — 16A, 32A, and 64A — the isolator is installed directly in the shore power earth conductor, in series between the shore earth connection and the vessel's earth network.\u003c\/p\u003e\n\u003cp\u003eThe galvanic isolator works by using two silicon diodes connected in an anti-parallel configuration. In this arrangement the diodes allow AC fault current to pass in both directions — ensuring the safety earth remains fully functional for personal protection and RCD operation in the event of a fault — but block any DC current below the diode conduction threshold of approximately 1.4 VDC. Since the electrochemical potential difference between dissimilar metals in seawater is typically below 1.4V, the isolator prevents galvanic currents from flowing between the vessel and the marina earth system without compromising the integrity of the safety earth circuit.\u003c\/p\u003e\n\u003cp\u003eThe isolator is distinct from a full galvanic isolation transformer, which provides complete electrical isolation between shore power and the vessel. The galvanic isolator is a lower-cost solution that addresses the most common cause of galvanic corrosion — stray DC currents via the shore earth — while retaining the direct earth connection required by electrical safety standards. For complete isolation, the Victron Isolation Transformer range should be used instead.\u003c\/p\u003e\n\u003cp\u003eAll three models are fully potted in resin, housed in an anodised aluminium heatsink enclosure, and rated IP67 — making them suitable for installation in bilges, engine rooms, and battery compartments where moisture, oil, and condensation are present. M6 terminals accept appropriately sized earth cable connections. Each model is supplied with mounting hardware.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003ch4\u003ePrevents Galvanic Corrosion via Shore Power Earth\u003c\/h4\u003e\n\u003cp\u003eBlocks low-voltage DC galvanic currents below approximately 1.4 VDC from flowing through the shore power earth wire — protecting the vessel's hull, propeller, shaft, anodes, and through-hull fittings from the accelerated electrolytic corrosion caused by being connected to a marina earth network.\u003c\/p\u003e\n\u003ch4\u003eAnti-Parallel Diode Design — Safety Earth Remains Intact\u003c\/h4\u003e\n\u003cp\u003eTwo silicon diodes connected in anti-parallel allow full AC fault current to pass in both directions above the 1.4 VDC threshold — ensuring the shore power safety earth and RCD protection remain fully functional for personal safety, while blocking the sub-threshold DC galvanic currents that cause corrosion.\u003c\/p\u003e\n\u003ch4\u003eAvailable in 16A, 32A, and 64A Ratings\u003c\/h4\u003e\n\u003cp\u003eThree current ratings cover the full range of standard shore power connections: VDI-16 (16A) for single-phase 16A shore connections, VDI-32 (32A) for 32A shore connections, and VDI-64 (64A) for 63A shore connections on larger vessels. All three share the same M6 terminal connection and IP67 protection rating.\u003c\/p\u003e\n\u003ch4\u003eIP67 Fully Potted and Waterproof Construction\u003c\/h4\u003e\n\u003cp\u003eThe electronics are fully encapsulated in resin within an anodised aluminium heatsink enclosure rated IP67 — providing complete protection against dust ingress and temporary submersion, making all three models suitable for installation in bilges, engine rooms, and wet compartments.\u003c\/p\u003e\n\u003ch4\u003eHigh Peak Current Capability — Fault Current Safe\u003c\/h4\u003e\n\u003cp\u003ePeak surge current ratings of 1600A (VDI-16), 3200A (VDI-32), and 6000A (VDI-64) for 20 milliseconds ensure the isolator can withstand the high transient fault currents that occur during earth fault events — allowing the RCD to trip and clear the fault safely without destroying the isolator.\u003c\/p\u003e\n\u003ch4\u003eSimple Series Installation in Shore Earth Cable\u003c\/h4\u003e\n\u003cp\u003eInstalled in series in the shore power earth (PE\/green) conductor, between the shore earth connection and the vessel's earth busbar — ensuring all vessel earth connections are protected by the isolator. Installation requires no configuration, programming, or power supply — it is a fully passive device.\u003c\/p\u003e\n\u003ch4\u003eLower-Cost Alternative to Isolation Transformer\u003c\/h4\u003e\n\u003cp\u003eThe galvanic isolator addresses DC galvanic corrosion via the shore earth at significantly lower cost and space than a full isolation transformer.
