Fuses & Circuit Breakers

Best Practices and ABYC standards state that every positive wire on the boat outside the engine starting circuit must have circuit protection. When excessive current flows in an electrical circuit, wire insulation can melt and possibly start a fire

Circuit breakers and fuses protect the wire in electrical circuits. Blue Sea Systems extensive selection of circuit breakers, fuses, fuse holders, and fuse blocks fives boaters a range of choices for main and branch circuit protection. To help select the right size wire and proper fuse or circuit breaker, Blue Sea Systems offers our Circuit Wizard

The demand for ignition protected circuit protection has increased. Blue Sea SystemsSafety and SafetyHub Fuse Blocks are specifically designed for use in environments with explosive fumes, such as an engine room or fuel storage locker.
