Disjunctor serie 285 - Montare panou 40 A

The 285 series circuit breaker stands out for its ability to be manually reset after tripping, unlike traditional fuses which require replacement after each overcurrent or short circuit. This provides significant convenience and cost savings, especially in a marine environment.

This BLUE SEA circuit breaker is specifically rated for a nominal current of 40 amperes (40 A). It is designed to protect marine electrical circuits where the maximum load does not exceed this value.

The BLUE SEA 285 series circuit breaker provides essential protection against overcurrent (overloads) and short circuits. It automatically cuts off power to the circuit in case of failure, preventing damage to equipment and fire hazards.

Yes, this circuit breaker is specifically designed to withstand demanding marine environments. Its construction ensures durability and stable performance in the face of humidity, salt, and vibrations typical of nautical applications.

Blue Sea Systems' 285 series circuit breakers are thermal circuit breakers. They respond to heat generated by prolonged overcurrent, making them effective for overload protection.

Although designed for demanding marine environments, this circuit breaker can be used in other applications requiring overcurrent and short-circuit protection, provided that electrical and environmental specifications are met. It is particularly robust.

The reset button allows manual restoration of power to the circuit after tripping due to an overcurrent or short circuit. Before resetting, it is recommended to identify and correct the cause of the trip.

Yes, Blue Sea Systems 285-series circuit breakers are certified "ignition protected" per SAE J1171. This means they are designed not to produce sparks capable of igniting fuel vapors in an engine compartment.

This circuit breaker is designed for panel mounting. This means it integrates directly into a cutout made in an electrical panel or control panel, providing a clean finish and easy access.

The exact contents of the package may vary. Typically, panel-mounted circuit breakers such as the 285 series are supplied with the nuts and washers required to secure the unit to the panel. Mounting screws for the panel itself or for wiring are generally not included.

Although exact dimensions are not provided in the textual description, a dimensioned technical drawing is available (reference 7842b4d1.jpg). It is essential to consult this diagram to obtain the precise measurements required for correct installation.

This circuit breaker can be installed in any position (vertical, horizontal, or tilted) without affecting its performance, provided that access for resetting and visibility of the indicators are maintained.

For the electrical installation, you will need basic tools for marine wiring, such as wire strippers, crimping pliers for terminals, and screwdrivers. A multimeter is also useful for checking connections and continuity.

Blue Sea Systems 285 series circuit breakers are compatible with 12V DC, 24V DC, and 32V DC marine electrical systems. It is critical to ensure that your system voltage does not exceed the breaker's maximum rating.

This circuit breaker is designed for individual circuit protection. While it can protect a group of devices connected to the same circuit, it is important that the sum of their power consumption does not exceed 40 amperes and that the circuit wiring is appropriately sized. For optimal protection, each major device should ideally have its own dedicated protection.

Yes, its panel-mount design makes it easy to integrate into existing electrical panels. It is important to check the dimensions of the required cut-out to ensure physical compatibility with the available space in your panel.

No, Blue Sea Systems 285 series circuit breakers are specifically designed for direct current (DC) systems and must not be used with alternating current (AC) systems. Using them with AC could compromise their protective performance and safety.

Yes, this circuit breaker can be used in systems powered by lithium batteries, provided the system voltage (12V, 24V, 32V DC) and maximum current (40A) comply with the circuit breaker’s specifications. It is essential to ensure the circuit breaker is correctly sized for the load and the battery’s potential short-circuit current.
