What phrase should identify ignition protection on the galvanic isolator if applicable?

The phrase "Ignition Protected" is specifically used to indicate that the device, including a galvanic isolator, has been designed and tested to prevent ignition of flammable gases or vapors that may be present in a marine environment. In situations where combustible materials are a concern, such as on boats and vessels, it is vital to ensure that electrical components do not pose a risk of igniting these materials. The "Ignition Protected" designation signals that the equipment meets necessary standards for safety against ignition, making it suitable for use in marine settings where such hazards are prevalent.

The other options do not convey the same specific assurance about ignition risks. While terms like "Marine Safety Rated" or "Certified Marine Standard" may imply safety features, they do not clearly indicate that the device has undergone specific testing for ignition protection. "Electrical Hazard Safe" suggests a general degree of safety around electrical risks but lacks the specific focus on ignition protection that is crucial in marine applications. Therefore, "Ignition Protected" is the most relevant and accurate term to identify this essential safety feature of a galvanic isolator.
