Disjunctor serie 285 - Montaj la suprafață 80 A

The BLUE SEA 285 series circuit breaker is an electrical protection device designed for marine environments. It protects circuits from overcurrent and short circuits, thereby preventing equipment damage and fire risks. This specific model is an 80-amp circuit breaker.

An 80-amp circuit breaker is used to protect electrical circuits powering high-current equipment, such as inverters, bow thrusters, windlasses, or large-capacity battery charging systems aboard a boat. It provides automatic shutdown in case of overload.

This circuit breaker is designed for surface mounting. This means it is fixed directly to a wall or panel using screws, without requiring any cutout in the support for installation. The connection terminals are then accessible for wiring.

Yes, the BLUE SEA Series 285 circuit breaker is specifically designed for marine applications. It is made with corrosion-resistant materials and is built to operate reliably in the demanding conditions encountered on board boats, such as moisture and vibrations.

The BLUE SEA 285 series circuit breaker is designed for direct current (DC) systems and can handle voltages up to 48V DC. It is commonly used in 12V, 24V, and 48V systems on vessels.

Yes, the BLUE SEA 285 series circuit breaker is "ignition protected" in accordance with SAE J1171. This means it can be safely installed in a boat's engine compartment where gasoline vapors may be present, without risk of causing an explosion.

This circuit breaker is a manual reset model. After tripping due to overload or short circuit, simply press the reset button to restore power to the circuit once the cause of the trip has been identified and corrected.

It is essential to use cables with the appropriate cross-section for the 80-ampere load and circuit length, in accordance with marine standards (e.g., ABYC). The circuit breaker terminals are typically threaded studs designed for heavy-duty cable lugs, ensuring a secure and low-resistance connection.

The interrupting rating (AIC - Ampere Interrupting Capacity) of the Blue Sea Systems 285 series is 3000 amperes at 48V DC. This value indicates the maximum current it can safely interrupt during a short circuit without being damaged.

Yes, a circuit breaker like this one can replace a fuse of the same rating (80 A) for protecting a circuit. The main advantage is that it can be manually reset after tripping, unlike a fuse which must be replaced.

Yes, this circuit breaker is fully compatible with 12V DC and 24V DC marine electrical systems. Its maximum 48V DC rating makes it versatile for various onboard voltage configurations.

Installing this circuit breaker typically requires standard marine electrical tools such as screwdrivers, wire strippers, crimping pliers for cable terminals, and possibly a drill for mounting holes. No specialized tools are required.

Blue Sea Systems' 285 series circuit breakers are designed to operate within a wide temperature range, typical of marine environments, generally from -40°C to +85°C. This ensures their reliability in various climatic conditions.

The choice of the circuit breaker's amp rating must match the maximum consumption of the equipment or circuit it protects, while being lower than the wiring's current capacity. For this model, it is 80 amperes, making it suitable for high loads. It is critical to consult your equipment specifications and wire gauge tables.

The connection terminals on this circuit breaker are robust threaded studs. Although exposed for cable connections, the breaker itself is designed to be weather-resistant. Use insulated terminals and ensure connections are tight and protected from excessive moisture.

Yes, the reset button on the BLUE SEA 285 series circuit breaker also serves as a visual indicator. When in the "ON" position, the button is recessed. If it has tripped, the button pops out, clearly indicating that the circuit is open and the breaker has acted to protect the system.
