ProMariner ProSafe FailSafe 30-Amp Galvanic Isolator

The ProMariner ProSafe FailSafe 30A Galvanic Isolator is ABYC A-28 compliant, UL certified and ISO 8846 ignition protected, with gold-plated terminations.

Gold-plated terminations are the detail worth noting, and they address a specific failure in this application. An isolator sits in the safety ground path permanently, and a corroded connection there raises resistance in exactly the circuit that must stay low-resistance for fault protection to work.

Thirty amps matches the shore service most recreational boats are wired for, so it is the common size in the range. The isolator rating should equal or exceed the inlet rating rather than being chosen independently.

FlatPack semiconductor technology blocks the low-voltage galvanic currents that corrode bonded underwater metals while letting fault current pass when needed. The fail-safe design eliminates the separate dedicated monitor some non-fail-safe isolators require, and if the isolator itself fails the ground connection is preserved.

• Gold-plated terminations resist corrosion in the ground path
• Corrosion there raises resistance where it must stay low
• 30A, the common recreational shore service
• Fail-safe, so no separate monitor is required
