Newmar GI-60-FS 60A Galvanic Isolator with Fail Safe

Shield Your Vessel from Galvanic Corrosion with Advanced Protection

Boat owners know the frustration of rapid zinc anode wear and unexpected corrosion on through-hulls, shafts, and propellers. These issues often stem from stray low-voltage DC currents sneaking in via shore power connections between the AC safety ground and your boat's DC bonding system. This "galvanic action" silently eats away at protective metals, leading to costly haul-outs and repairs.

Enter a reliable solution designed for cruisers, sailboats, and yachts: a 60-amp galvanic isolator that blocks those harmful currents while preserving the essential safety ground path. By installing it inline, you slash zinc replacement frequency and extend the life of your underwater hardware, keeping maintenance budgets in check and your time on the water.

Standout Features for Marine Reliability

• Fail-Safe Design: In the rare event of component failure, it automatically maintains a solid ground connection, prioritizing safety without compromising protection.
• Robust Testing: Handles up to 50°C ambient temperatures and certified to UL1500 for ignition protection, ensuring performance in hot engine rooms or sunny marinas.
• High-Capacity Surge Handling: Rated for massive 5000-amp short circuits, providing peace of mind during power fluctuations.
• Versatile Voltage Support: Works seamlessly with 115-230V shore power systems common worldwide.
• Compact Footprint: Measures just 260 x 190 x 65 mm, fitting easily into tight bilge spaces or electrical panels.

Unlike basic isolators, this model exceeds ABYC A-28 2019 standards, incorporating a large capacitor for a low-impedance backup path. This diverts any high AC fault currents to ground instantly, adding an extra layer of electrical safety.

How Galvanic Isolators Work to Protect Your Boat

At its core, the device uses back-to-back diodes to create a one-way barrier for DC currents. Stray voltages up to 1.4 Vdc get blocked, preventing electrolysis that accelerates zinc sacrifice. Yet, if a dangerous AC fault occurs, the diodes forward-bias, shunting current safely away.

For boaters docking at varying marinas, where dissimilar metals on neighboring vessels can form unintended batteries, this isolation is crucial. It maintains your boat's electrical independence, reducing "galvanic corrosion" risks without isolating you from life-saving ground faults.

Pro Tip: Pair it with regular zinc inspections and a solid bonding system for comprehensive cathodic protection. Many owners report zincs lasting 2-3 times longer after installation.

Why This Fail-Safe Model Stands Above the Rest

Standard isolators might fail open, severing your ground path and creating hazards. This unit's innovative fail-safe ensures continuity, meeting the latest marine codes. It's built for real-world abuse: humidity, vibration, and heat that plague marine environments.

Ideal for larger vessels drawing higher shore power loads, it handles 60 amps continuously. Yacht captains and liveaboard sailors praise its durability, often citing fewer electrolysis-related dry-dockings.
