The Blue Sea 187 series 50 A circuit breaker is designed to protect marine DC electrical circuits against overcurrents. It functions as a safety switch that trips automatically in the event of overload or short circuit, cutting power to prevent damage to equipment or wiring.

Unlike a traditional fuse that must be replaced after tripping, the 187 series circuit breaker allows for simple and quick manual resetting. This eliminates the need to carry spare fuses and makes it easier to restore the circuit after resolving an overcurrent issue.

Yes, this circuit breaker is specifically designed for marine applications. It is robust and offers better resistance to vibrations compared to standard fuses, ensuring increased reliability in nautical environments.

This circuit breaker uses a purely thermal tripping mechanism. It responds to overcurrents based on circuit heating, making it reliable for general circuit protection.

Yes, the 187 series circuit breaker can be used as the main switch for a specific piece of equipment. Its manual reset mechanism allows it to be turned on or off manually, in addition to its automatic overcurrent protection function.

The Blue Sea 187 series circuit breaker is designed to operate within a wide temperature range, from -40°C to +85°C. This ensures its reliability in various marine weather conditions.

Yes, this circuit breaker is protected against ignition per SAE J1171. This feature is essential for safety in boat engine compartments where flammable vapors may be present.

Thermal circuit breakers, such as the 187 series, are generally more compact and cost-effective. They are suitable for applications where ultra-fast tripping speed is not the absolute priority, but where reliability and compactness are essential for panel mounting.

This circuit breaker is designed for panel mounting. This means it is installed in a cutout made in an electrical panel or mounting surface, with the front face of the circuit breaker flush with the surface.

For installation, you will typically need a hole saw or a drill with a suitable bit to cut the panel opening, a screwdriver to secure the circuit breaker and connect the cables to the terminals, and a wrench to tighten the terminal nuts.

Typically, the circuit breaker comes with the necessary nuts and washers for the terminals, as well as a sealing gasket for panel mounting. The mounting hardware for securing the circuit breaker to the panel (screws) may need to be purchased separately, depending on your installation specifications.

This circuit breaker is designed for direct current (DC) systems and can support a maximum voltage of 48V DC. It is therefore compatible with the commonly used 12V, 24V, and 48V systems in marine applications.

This 50 A circuit breaker is ideal for protecting circuits powering high-consumption equipment such as windlasses, voltage converters, medium-sized battery charging systems, or as main circuit protection for moderate to high-power electrical installations.

No, the Blue Sea 187 series circuit breaker is specifically designed for direct current (DC) systems. It must not be used for protecting alternating current (AC) circuits, as its tripping and breaking characteristics are not suited for this type of current.
