Winner of the prestigious 2007 IBEX Award for Innovation, ProSafe FS (Fail Safe) Galvanic Isolators maximize anode life and protect metal parts on boats against galvanic corrosion. Installation is simplified by the fact that they do not require a dedicated monitor to verify operational status as required by non-fail-safe-certified designs. 30 Amp models are built on robust flat-pack semiconductor platforms to ensure that your boat's AC ground will continue to work in the unlikely event the isolator fails. Terminals are gold-plated for long life.
