Rafmagnsrofi BLUE SEA 285 - Yfirborðsfesting 50 A

The BLUE SEA 285 series circuit breaker is designed to protect DC electrical circuits aboard vessels from overloads and short circuits. It interrupts current flow in case of failure to prevent damage to equipment and wiring.

This BLUE SEA 285 series circuit breaker model has a rated current of 50 amperes. It is suitable for applications requiring protection for high currents.

Yes, the BLUE SEA Series 285 circuit breaker is manually resettable. This means that after an overload or short circuit, it can be reactivated by pressing its button without requiring replacement like a fuse.

This circuit breaker is specifically designed for direct current (DC) circuits, commonly used in marine applications.

With its 50 A rated current, this circuit breaker is suitable for protecting equipment requiring high current draw such as windlasses, small bow thrusters, or main power circuits for complex onboard electronic systems.

The main difference is that the Series 285 circuit breaker is manually resettable. Unlike fuses, which must be replaced after an overload, this circuit breaker can be reactivated, providing a more convenient and cost-effective long-term solution.

Yes, this circuit breaker is designed by BLUE SEA Systems, a brand specializing in marine electrical equipment. It is therefore suitable for the demanding conditions of the nautical environment, providing reliable protection for marine applications.

The BLUE SEA 285 series circuit breaker is designed for direct current (DC) systems. It is typically compatible with voltages up to 48 Volts DC, making it suitable for most standard marine electrical installations.

Blue Sea Systems 285 series circuit breakers are designed for marine environments and are generally splash-resistant. They are often rated as 'ignition protected,' making them safe for use in engine compartments where flammable vapors may be present. However, they are not designed to be submerged.

This circuit breaker is designed for surface mounting. This means it is fixed directly onto a flat surface such as an electrical panel or a control panel.

Surface mounting simplifies installation as it does not require complex cutting into a panel. It is secured with screws (not included), and cable connections are made via screw or stud terminals, making the process relatively straightforward for an electrician or a skilled DIYer.

For installation, you will usually need basic tools such as a screwdriver for terminals and mounting screws, wire strippers and crimping pliers to prepare cables, and a drill for mounting holes if required.

Blue Sea 285 series circuit breakers can generally be mounted in any orientation (vertical, horizontal, or tilted) without affecting performance, provided connections are secure and the reset button remains accessible.

Yes, the BLUE SEA 285 series circuit breaker is compatible with 12V DC and 24V DC marine electrical systems, as well as higher voltages up to 48V DC. Its 50A rated current makes it suitable for protecting high loads on these voltages.

No, this circuit breaker is specifically designed for direct current (DC) circuits. It must not be used for alternating current (AC) applications because it is not designed to handle AC’s specific characteristics.

The circuit breaker is compatible with cables whose cross-section is suitable for handling 50 amperes, in accordance with ABYC standards or equivalent. The terminals are typically designed to accept ring terminals or bare wires of heavy gauge, suitable for this current rating.

The BLUE SEA 285 series circuit breaker is designed to be maintenance-free. It is recommended to periodically check cable connections to ensure they remain tight and to ensure the circuit breaker is not exposed to physical damage or excessive corrosion in very humid or salty environments.
