Jistič série 285 - povrchová montáž 50 A

The BLUE SEA 285 series circuit breaker is designed to protect DC electrical circuits on board vessels against overloads and short circuits. It interrupts the current flow in case of failure to prevent damage to equipment and cables.

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 285 series 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) electrical circuits, commonly used in marine applications.

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

The main difference is that the 285 series circuit breaker can be manually reset. 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 suited to the stringent requirements and harsh conditions of the marine environment, providing reliable protection for marine applications.

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

The BLUE SEA 285 series circuit breakers are designed for the marine environment 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 skilled DIYer.

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

BLUE SEA's 285 series circuit breakers can generally be mounted in any orientation (vertical, horizontal, or tilted) without affecting their performance, provided the 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 heavy loads at these voltages.

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

The circuit breaker is compatible with cables whose cross-section is suitable for carrying a current of 50 amperes, in accordance with ABYC standards or equivalent. The terminals are generally designed to accept ring terminals or large-gauge bare wires, 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 saline environments.
