Blue Sea 7040 187 - Series Thermal Circuit Breaker - 60Amp

The Blue Sea 7040 187-Series Thermal Circuit Breaker – 60Amp is an essential marine-grade protection system designed for serious boaters managing high-demand electrical loads. This breaker is ideal for powering multiple 12-volt systems, thruster motors, or auxiliary engines, ensuring safety and reliability while out on the water.

Engineered specifically for both salt and fresh water environments, this breaker features a thermal-magnetic design that provides instant magnetic response for short circuits and slower thermal response for harmless startup surges. This design is particularly important for inductive loads such as pumps and compressors, protecting against sustained overload conditions that could lead to wiring damage or fire.

Ideal for anglers and cruisers, the Blue Sea 7040 allows for simultaneous operation of fish finders, livewells, trolling motors, and cabin systems without manual load management. Its compact size makes it easy to mount in marine-grade panel boxes, and it integrates seamlessly into existing Blue Sea Systems installations.
