ProMariner ProSafe FAILSAFE 30amp Galvanic Isolator [22034] - CWR-33330

ProMariner ProSafe FAILSAFE 30amp Galvanic Isolator [22034] - CWR-33330

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.

Features

• ProSafe FS 30 is built on robust FlatPack semiconductor platforms ensuring that in the event of a failure, the failure is safe by not compromising the ground continuity on-board when connected to AC Shore Power.
  
• ABYC A-28 July '08 Compliant and Fail Safe Certified
  Certified by Underwriters Laboratories (UL). Insures shore power safety ground wire is maintained through the isolator.
  
• Flat Pack High Power Semiconductors
  Robust high power diodes allow the FS Series to meet the new FailSafe criteria for conducting inrush currents of 3,000 amps for the required duration period.
  
• Ignition Protected
  Meets ISO 8846 and can be mounted within an engine compartment.
  
• Gold Plated Terminations

Q&A

Q: What is the ProMariner ProSafe FAILSAFE 30 Amp Galvanic Isolator 22034?
A: A marine‑grade 30 Amp galvanic isolator designed to reduce galvanic corrosion when your boat is connected to AC shore power by interrupting stray DC currents that cause metal corrosion.

Q: What does “FailSafe” mean?
A: “FailSafe” ensures the isolator safely maintains AC safety ground continuity even if the unit fails, without needing a separate monitor to verify operation as required by non‑FailSafe units.

Q: How does it protect my boat?
A: It interrupts galvanic current flowing between boats and the dock while still maintaining the safety ground, helping protect hull metal, props, outdrives, and sacrificial zincs from corrosion.

Q: What certifications and compliance does it have?
A: It’s ABYC A‑28 compliant, UL certified, and ignition protected to ISO 8846, so it’s engineered for safe marine electrical environments.

Q: What are key construction features?
A: Built with robust flat‑pack semiconductor diodes and gold‑plated terminations for corrosion resistance and dependable performance on AC shore power systems.

Q: What shore power systems is it compatible with?
A: Designed for single 30 Amp AC shore power applications (120/240 V AC), making it suitable for typical 30 A shore connections on boats.

Q: Why choose this galvanic isolator?
A: It offers FailSafe protection, easy installation, strong corrosion resistance, and certified marine safety — ideal for boat owners looking to protect underwater metals and extend zinc life while on shore power.

Maintenance Tips

• Check Terminals & Connections: Periodically inspect gold‑plated terminals and wiring for corrosion or looseness; clean and tighten for solid electrical contact.
• Keep Dry & Ventilated: Mount in a dry, well‑ventilated area away from direct moisture; dust or wipe dry to prevent corrosion on enclosure and connections.
• Inspect AC Shore Power Wiring: Ensure the green safety‑ground conductor and shore power connection are correct and intact to maintain proper operation and safety.
• Visual Check for Overheat Signs: Watch for discoloration or heat damage on wires and casing; excessive heat can indicate poor connections or overload.
• Confirm Failsafe Operation: Use a monitor or periodical testing (if equipped) to verify the isolator hasn’t failed; a failed isolator should be replaced to maintain corrosion protection.
• Avoid Harsh Cleaning: Do not spray water or corrosive cleaners on the unit; use a dry cloth and light corrosion inhibitor on exposed metal parts.
