HYPERTECH 49200 Galvanic Isolator for Marine Shore Power Systems

Used In 115 or 230 Volt Single or 2- Phase; 50 Amp; For Aluminum or Wooden Hulls

Protect your marine electrical system from galvanic corrosion with the HYPERTECH 49200 Galvanic Isolator. This component is designed for use with boats and other watercraft connected to shore power, helping reduce the damaging effects of stray low-voltage electrical currents that can travel between a vessel and the marina grounding system. By helping interrupt galvanic current while preserving the intended safety-grounding path, the isolator supports reliable electrical protection without compromising proper shore-power operation.
The HYPERTECH 49200 Galvanic Isolator is a practical addition to marine electrical systems where corrosion protection is a priority. Galvanic corrosion can affect underwater metals, including propellers, shafts, trim components, through-hulls, and other bonded hardware. Installing an appropriate isolator can help limit unnecessary metal loss and extend the service life of these components when the vessel is connected to external AC power. It is intended to complement proper bonding, grounding, anode maintenance, and routine electrical inspections.
Built for straightforward integration into compatible marine shore-power installations, this galvanic isolator is suitable for replacement applications, system upgrades, and preventative maintenance. Verify electrical compatibility, installation requirements, and local marine-code provisions before fitting the component. Professional installation is recommended when working with shore-power wiring or vessel grounding systems. The HYPERTECH 49200 provides a focused solution for boat owners, marine technicians, and service professionals seeking dependable galvanic-current protection in a compact electrical component.
For best results, inspect the vessel’s bonding network, shore-power connections, sacrificial anodes, and underwater hardware as part of a complete corrosion-control program. The isolator should be installed and maintained according to the manufacturer’s guidance and the requirements of the specific vessel. With its marine-focused purpose and HYPERTECH engineering, Part Number 49200 helps support safer, more durable shore-power operation and long-term protection of essential underwater metal components.
