It eliminates the risk of stray current corrosion and electric shock hazard from faulty shore supplies, and handles automatic voltage conversion between 115V and 230V AC systems. Suited to professional marine and mobile power installations where grid isolation is a safety requirement.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4500W continuous power rating, suitable for high-load onboard or mobile AC systems.\u003c\/li\u003e\n  \u003cli\u003eAutomatic 115V\/230V voltage conversion, allowing connection to both North American and European shore power supplies without manual reconfiguration.\u003c\/li\u003e\n  \u003cli\u003eGalvanic isolation breaks the direct electrical connection between shore earth and vessel or vehicle chassis, preventing stray current corrosion.\u003c\/li\u003e\n  \u003cli\u003eEliminates shock hazard caused by faulty or poorly earthed shore power pedestals.\u003c\/li\u003e\n  \u003cli\u003eCompact, robust toroidal transformer construction with a rated weight of 21.8 kg, typical of high-quality toroidal core design.\u003c\/li\u003e\n  \u003cli\u003eSKU ITR050452042 — Victron Energy OEM product with GTIN 8719076075202.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eShore power supplies at marinas and campsites are not always clean or correctly earthed. A direct connection between shore earth and a vessel's hull creates a galvanic cell with neighbouring metalwork in the water, accelerating corrosion of anodes, propellers and through-hull fittings. The Victron Isolation Transformer breaks this path entirely by providing full galvanic isolation between the shore supply and the onboard AC system.\u003c\/p\u003e\n\n\u003cp\u003eThe auto 115\/230V function means the transformer detects and converts between the two most common shore power voltages. This is particularly relevant for vessels or vehicles that travel between the UK and Europe and North America, or for installations where the shore supply voltage is not guaranteed. At 4500W, the unit supports meaningful onboard loads including air conditioning, battery chargers, inverter-chargers and galley equipment running simultaneously.\u003c\/p\u003e\n\n\u003cp\u003eToroidal transformer construction is standard in quality marine isolation transformers. It offers a lower magnetic field footprint and better efficiency compared to conventional laminated core designs, which matters in confined bilge or locker installations where heat and space are concerns.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24; border-collapse: collapse; width: 100%;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f87c24; color: #ffffff;\"\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eITR050452042\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eRated Power\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e4500W\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eVoltage (Auto)\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e115V \/ 230V AC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e21.8 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGTIN\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8719076075202\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMarine shore power connections on sailing yachts, motorboats and narrowboats where galvanic isolation is required.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and caravans connecting to campsite hook-up supplies with uncertain earthing quality.\u003c\/li\u003e\n  \u003cli\u003eVessels travelling between 115V (North American) and 230V (European) shore power infrastructure.\u003c\/li\u003e\n  \u003cli\u003eAny installation where a direct shore earth-to-chassis connection must be avoided for corrosion or safety reasons.\u003c\/li\u003e\n  \u003cli\u003eCommercial and charter vessels where electrical safety compliance demands full isolation from shore supply.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron Energy Isolation Transformer 4500W Auto 115\/230V\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis transformer handles mains AC voltages and must be installed by a qualified electrician or a competent marine electrical engineer.
