Blue Sea Systems' fuse blocks that meet the U.S. Coast Guard ignition protection requirements include the MAXI®, ST-Blade Battery Terminal Mount, ST-Blade Compact, Terminal MRBF, some Class-T models, Safety, and SafetyHub Fuse Blocks. The U.S. Coast Guard states: An electrical component that is “ignition protected” is capable of operating in an explosive environment without igniting that environment. “Ignition protection” of electrical devices is accomplished by the use of seals, flame arrestors and potting (sealing), or a combination of such means.
