Product Details

The NewMar GI-30-FS is a 30-amp fail-safe galvanic isolator designed to protect boats and yachts from galvanic corrosion while maintaining critical AC safety ground integrity. Installing this isolator between the AC safety ground and DC bonding system blocks low-voltage DC currents that cause corrosive action on metallic components submerged in saltwater, significantly extending the life of sacrificial anodes and underwater metals.

Key Features:

  • Fail-safe design meets latest ABYC A-28 2019 requirements for marine galvanic isolators
  • UL1500 certified for Ignition Protection in marine environments
  • Large capacitor provides secondary low-impedance path for AC fault current to ground
  • Tested to 50°C ambient temperature for reliable performance in engine rooms
  • Automatic ground connection maintained in event of isolator failure
  • Blocks stray DC currents up to 1.4 VDC while passing AC fault current instantly

Technical Specifications:

  • Maximum Current Rating: 30 Amps continuous
  • Shore Power Compatibility: 115-230V AC
  • Maximum Short Circuit Rating: 5000 Amps
  • Stray Current Protection: Up to 1.4 VDC
  • Dimensions: 7.87" L × 7.44" W × 2.70" H (200 × 189 × 68.5 mm)

This galvanic isolator represents a significant cost savings by reducing boat haul-out frequency and zinc anode replacement while ensuring compliance with marine electrical safety standards. Professional installation recommended in accordance with ABYC standards.

Fast delivery.

Super easy ordering.

Fast service and delivery

Great

Nice and easy

The only thing that would have been better is if the tracking number brought up a map or something more than the order that was placed. Can't wait to install my parts. Thanks.
