Galvanic Isolator and Electrical Surge Protector

Galvanic Isolator and Electrical Surge Protector - Plug In

Galvanic Isolator rated 400 Amps

Electrical Surge Protection 4,000 amps

The Gi-120/P/CP is a 3-in1 device, including a High-quality Galvanic Isolator, Earth Leakage protection and Electrical Surge Protector. It's designed to safeguard against Galvanic currents, Earth Leakage, and to protect your boat’s electrical system from Electrical Power Surges, preventing damage from nearby lightning strikes, power grid fluctuations, and other electrical spikes.

Essential equipment when when using a portable generator, which often cause power instability.

Installation is simple—just plug it into your electric hookup cable. It completely blocks Galvanic corrosion currents, preventing damage to your boat, while also regulating power surges to keep your electrical and electronic equipment safe.

FULLY Guaranteed

Fitting a Plug In Galvanic Isolator/Surge Protector couldn’t be simpler. You don’t need any electrical knowledge or tools, and fitting takes about 30 seconds. And it's guaranteed to do the job - without the hassle of complicated wiring. 

 3 in 1 protection

Protects your boat from three major electrical threats:

• Galvanic currents – These can corrode the boat’s hull and underwater fittings.
• Earth leakage – Similar to galvanic currents but far more aggressive, posing an even greater risk to your boat’s structure and components.
• Power surges – A sudden surge can instantly damage your boat’s electrical system and anything connected to it.

Protects against Galvanic Currents, Earth Leakage and Power Surges

This device protects your boat from galvanic corrosion and earth leakage, and also features a highly effective power surge protector. You can think of it as three essential protections all in one compact unit.

Galvanic Isolation and Earth Leakage protection

This two-stage galvanic isolator also features earth leakage monitoring with two high intensity LED indicators. These LEDs continuously check your boat’s earth connection, alerting you to potential corrosion risks or dangerous mains voltage leaks. If a problem is detected, the clear, easy-to-read indicators will warn you immediately.

Surge Protector

This device protects your boat from power surges caused by nearby lightning strikes and fluctuations in the mains voltage. Unlike many home surge protectors that use just two varistors, this model has three varistors for superior protection. These components instantly absorb and dissipate power surges, ensuring your boat's electrical system, (and anything connected to it), remains safe.

Extra Protection. Under the bonnet, there is our "2-stage Protection System", which protects your hull against electrical noise and Galvanic & Stray Voltages up to twice as high as a normal Galvanic isolator.

How It Works...

Check your earthing at a glance.

Both Lights OFF: Your Galvanic isolator is operating normally. No action required, so just check back occasionally to ensure that all's well.

One Light ON: If either of the lights are on, it indicates DC leakage. This can cause severe corrosion to your boat. Our instructions give clear basic advice on how to resolve the problem.

BOTH lights ON: If both lights are ON, this indicates AC leakage, usually from the mains wiring or a connected appliance. AC leakage can be a danger to life. Please see instructions for help in rectifying the problem.

This Galvanic isolator is designed to stop galvanic and earth leakage currents while also protecting against electrical power surges. Its design ensures that the safety electrical earth remains unaffected, keeping you fully protected from electrical faults. It offers a quick and simple solution to the corrosion that your boat is likely experiencing unless a galvanic isolator is installed. Additionally, our 2-Stage Protection System provides protection against voltages up to twice that of a standard galvanic isolator. The surge protection feature helps safeguard the complex electronic equipment commonly found on modern boats.

The Gi120/P/CP has a 2 YEAR guarantee against faulty materials and manufacture. We also offer a FREE checking service for your peace of mind. (You may want to get your Galvanic isolator checked in the event of a major electrical fault, lightning strike etc).

If your mains connecting cable has a socket that matches the measurement in the photo, this is the correct Galvanic isolator for you. This size fits 99% of canal/river boats, and the majority of other types of vessel.
