ProMariner ProSafe FAILSAFE 60amp Galvanic Isolator [22074] - CWR-33331

ProMariner ProSafe FAILSAFE 60amp Galvanic Isolator [22074] - CWR-33331

ProSafe FS installs easily and does not require a dedicated monitor to verify the operational status of the galvanic isolator as required by non FailSafe Certified galvanic isolators.

What our Experts Think

• Robust 60 Amp Galvanic Protection
  Provides stronger isolation capacity for larger marine electrical systems, helping prevent corrosive current from damaging underwater metals and thru‑hulls.
• Fail‑Safe Reliability
  Engineered to maintain isolation integrity even under fault conditions — giving added confidence in protecting your vessel’s metal components.
• Marine‑Grade Durability
  Constructed with corrosion‑resistant materials and rugged housing to withstand moisture, vibration, and harsh saltwater environments.
• Simple Integration
  Designed for straightforward installation into existing or new electrical systems without complex setup.
• Versatile System Compatibility
  Suitable for sailboats, powerboats, and larger vessels with higher current demands.

Q&A

Maintenance Tips

• Clean Connections Periodically: Inspect the gold‑plated terminals and AC shore power ground connections for corrosion or salt buildup; wipe with a dry cloth and use a light corrosion inhibitor as needed.
• Ensure Dry Mounting Location: Install and keep the isolator in a dry, ventilated area to minimize moisture exposure and prevent corrosion around connections.
• Check Shore Power Wiring: Periodically examine shore power cable insulation, green ground wire continuity, and clamps to confirm secure, corrosion‑free connections to the isolator.
• Watch for Heat & Discoloration: After plugging into shore power, feel for excessive heat or visible discoloration around terminals — this can indicate poor contact or overload.
• Inspect Mounting Hardware: Ensure screws and mounting hardware are tight and free from corrosion to maintain solid electrical grounding.
• Test Ground Continuity Occasionally: Using a multimeter, check the AC safety ground continuity from the shore inlet through the isolator to the boat’s bonding system; abnormal readings may point to wiring issues.
